Quick Start
The AvaSpec spectrometers are easy to set up, allowing the user to start collecting data within
minutes. The pages in this section provide instructions on setting up your system, installing and
configuring the software and connecting sampling optics.
1.1
Installing the AvaSpec
First install the AvaSoft software from the CD-rom, before you connect your AvaSpec spectrometer
to your computer. If you connect the AvaSpec first, you will not be able to use your spectrometer.
One of the options in the main menu which is shown after the CD-rom is inserted in the CD-rom
drive, is to install AvaSoft software. After selecting this option, a submenu is displayed in which the
spectrometer configuration can be selected. The AvaSpec-USB1 group of spectrometers should be
selected to install AvaSoft for one of the following spectrometer types:
AvaSpec-128 or AvaSpec128-y
AvaSpec-256 or AvaSpec256-y
AvaSpec-1024 or AvaSpec1024-y
AvaSpec-2048 or AvaSpec2048-y
AvaSpec-2048FT or AvaSpec2048FT-y
In which y represents the number of spectrometer channels.
The AvaSpec-USB2 group of spectrometers should be selected to install AvaSoft7 for one of the
following spectrometer types:
AvaSpec-128/256/1024/2048/2048L/2048x14/3648/ULS2048/NIR256-USB2.
Other Avantes Products for which AvaSoft can be installed are AvaMouse for which a separate
manual is available.
Instructions below are for the AvaSpec-USB1 and -USB2 spectrometers, -Bluetooth® instructions are
found in section 1.1.1.
New since AvaSoft 7.3.1 Windows-Vista 64 bit support for AvaSpec-USB2 platform only
New AS5216.DLL with support for Windows Vista x64. The AS5216.DLL now detects whether it is
running on a 64 bit version of Windows, and will then use the WinUSB device driver, instead of the
32 bit Avsusb2.sys kernel mode device driver. WinUSB is Microsoft‟s own USB driver, that is
distributed with Vista. The install package for the as5216.dll will configure WinUSB to support the
AS5216 hardware. The DLL and AvaSoft are all still 32 bit programs, but they will now work on Vista
x64 (in the so-called WoW64 mode).
Installation Dialogs
The setup program will check the system
configuration of the computer. If no
problems are detected, the first dialog is
the “Welcome” dialog with some general
information.
In the next dialog, the destination directory
for the AvaSoft software can be changed.
The default destination directory is
C:\AVASOFT7USB2. If you want to install
the software to a different directory, click
the Browse button, select a new directory
and click OK. If the specified directory does
not exist, it will be created.

In the next dialog, the name for the program manager group can be changed. The default name for
this is “AVANTES Software”.
After this, the “Start Installation” dialog is shown. After clicking the “next” button, the installation
program starts installing files.
During this installation, the installation program will check if the most recent USB driver has been
installed already at the PC. If no driver is found, or if the driver needs to be upgraded, the Device
Driver Installation Wizard is launched automatically, click Next
After the drivers have been installed successfully, the dialog at the right is displayed, click Finish.
After all files have been installed, the “Installation Complete” dialog shows up. Click Finish.
Connecting the hardware
Connect the USB connector to a USB port on your computer with the supplied USB cable. Windows
will display the “Found New Hardware” dialog. Select the (default) option to install the software
automatically, and click next. After the Hardware Wizard has completed, the following dialog is
displayed:
Click Finish to complete the installation.
Please note that if the spectrometer is
Connected to another USB port to which it has
not been connected before, the “Found New
Hardware Wizard” will need to install the
software for this port as well. For this reason,
this Wizard will run “NrOfChannel” times for a
multichannel AvaSpec-USB2 spectrometer
system. This, because inside the housing, the
USB ports for each spectrometer channel is
connected to a USB-Hub.
Windows Vista will install the driver automatically, without displaying the “Found New Hardware
Wizard” dialogs

1.3
Measuring and saving a spectrum
1. After starting AvaSoft, the green Start button needs to be clicked to start measuring.
2. Connect a fiber or probe to the light source and to the spectrometer input port(s) and set up the
experiment for taking a reference spectrum.
3. Adjust the Smoothing Parameters in the Setup menu (section 3.2.2) to optimize smoothing for
the Fiber/Slit diameter that is used (for –USB2 platform AvaSpecs optimal smoothing is preset
and stored on board in the EEPROM).
4. Now turn on the light source. Usually some sort of spectrum may be seen on the screen, but it is
possible that too much or too little light reaches the spectrometer at the present data collection
settings. Too much light means that, over a certain wavelength range, the signal is saturated
shown as a straight line at the maximum counts and the appearance of the label “saturated” in
the statusbar of the spectrometer channel. This can usually be solved by a shorter integration
time. The integration time can be changed in the main window, in the white box below the
start/stop button. If AvaSoft is collecting data, the start/stop button shows a red „stop‟ and the
integration time box is gray, indicating that it cannot be changed (USB1). After clicking the
„stop‟ button the data acquisition stops and the integration time can be changed. The result of
the changed integration time can be viewed after clicking the green „start‟ button. Try to adjust
the integration time, such that the maximum count over the wavelength range is around 90% of
the full ADC scale (14750 counts for the 14bit ADC, 59000 counts for the 16bit ADC). When at
minimum integration the signal is still too high, an attenuator, a neutral density filter or fibers
with a smaller diameter may be used. When not enough light reaches the spectrometer, likewise
a longer integration time should be entered.
5. When a good spectrum is displayed, turn off the light source.
6. Now save the Dark data. This is be done by File-Save-Dark from the menu or by clicking the
black square on the left top of the screen with the mouse. Always use Save Dark after the
integration time has been changed.
7. Turn on the light source again. Save the present spectrum as a reference by choosing File SaveReference from the menu or by clicking at the white square (next to the black one). Always use
Save Reference after the integration time has been changed. Now the
Transmittance/reflectance (T/R button) or Absorbance (A button) spectra can be obtained
online. To have a better look at the amplitude versus wavelength, the cursor button can be
clicked. A vertical line is displayed in the graph. If the mouse cursor is placed nearby this line,
the shape of the mouse cursor changes from an arrow to a „drag‟ shape. If this shape is
displayed, the left mouse button can be used to drag (keep left mouse button down) the line
with the mouse towards a new position. Moving this line shows the corresponding values of
wavelength and amplitude in the main screen. By clicking the red stop button, the data
acquisition is stopped and the last acquired spectrum is shown in static mode. The data
acquisition can be started again by clicking the same button, which now shows a green „Start‟.
8. To save the spectrum (in the mode chosen before), choose File-Save-Experiment from the menu,
or click the Save Experiment button from the button bar.
9. To improve the Signal/Noise ratio, a number of spectra may be averaged. To do this, the value
in the white average box in the main window (next to integration time) can be increased. The
value can only be changed in static mode. When AvaSoft is acquiring data, the average box
becomes gray (USB1 platform).

Miniature Fiber Optic Spectrometers
With the introduction of the USB2 platform spectrometers the setup of this chapter has slightly
changed, first you will find all spectrometers by ordering code and then you will find last paragraphs
of this chapter the connections for both USB1 platform and USB2 platform.
2.1
AvaSpec-128 Fiber Optic Spectrometer
The AvaSpec-128 Fiber Optic Spectrometer is
based on the AvaBench-45 symmetrical CzernyTurner design with 128 pixel Photo Diode Array.
The spectrometer has a fiber optic entrance
connector (standard SMA, others possible),
collimating and focusing mirror and diffractional
grating. A choice of 11 different gratings with
different dispersion and blaze angles enable
applications in the 360-1100nm range. The
AvaSpec-128 can be delivered with 2 platforms of
electronics; either with USB1.1 with 14 bit AD
converter or the new USB2.0 with 16 bit AD
converter. Applications for this instrument are
low cost color measurements. Digital IO ports enable external triggering and control of shutter and
pulsed light sources from the Avantes line of instruments.
The AvaSpec-128 is also available as dual channel or multiple channel instrument (up to 8 channels),
where all spectra are taken simultaneously.
The AvaSpec-128 comes with AvaSoft-basic, a complete manual, USB interface cable and a PS12V/1.0A power supply. AvaSoft-full and application software can be ordered separately.
Alternatively the AvaSpec-128-SPU has a switch to run on USB power or external power.
The new AvaSpec-USB2 has a USB2 interface with ultrafast datasampling of 8000 spectra per second
(with on board averaging) and datatransfer in 1.1msec and supports analog in-and outputs as well.
Optional Bluetooth (-BT) communication and an SD card for on-board saving of spectra can be
added. Multiple (up to 127) USB2 spectrometers with different detector types can be externally
coupled.
AvaSoft-full and application software can be ordered separately.

AvaSpec-256 Fiber Optic Spectrometer
AvaSpec-256
The AvaSpec-256 Fiber Optic Spectrometer is
based on the AvaBench-45 symmetrical CzernyTurner design with 256 pixel CMOS Detector
Array. The spectrometer has a fiber optic
entrance connector (standard SMA, others
possible), collimating and focusing mirror and
diffractional grating. A choice of 13 different
gratings with different dispersion and blaze
angles enable applications in the 200-1100nm
range. The AvaSpec-256 can be delivered with
2 platforms of electronics; either with USB1.1
with 14 bit AD converter or the new USB2.0
interface with 16 bit AD converter.
The AvaSpec-256 is specially suitable for low
noise applications. Digital IO ports enable external triggering and control of shutter and pulsed light
sources from the Avantes line of instruments.
The AvaSpec-256 is also available as dual channel or multiple channel instrument (up to 8 channels),
where all spectra are taken simultaneously.
The AvaSpec-256 comes with AvaSoft-basic, a complete manual, USB interface cable and a PS12V/1.0A power supply. AvaSoft-full and application software can be ordered separately.
Alternatively the AvaSpec-256-SPU has a switch to run on USB power or external power.
The new AvaSpec-USB2 has a USB2 interface with ultrafast datasampling of 1500 spectra per second
(with on board averaging) and datatransfer in 1.5msec and supports analog in-and outputs as well.
Optional Bluetooth (-BT) communication and an SD card for on-board saving of spectra can be
added. The AvaSpec-256-USB2 runs on USB power and comes with AvaSoft-basic, a complete manual
and USB interface cable. Multiple (up to 127) USB2 spectrometers with different detector types can
be externally coupled. AvaSoft-full and application software can be ordered separately.

AvaSpec-2048L Fiber Optic Spectrometer with larger pixels
AvaSpec-2048L
The AvaSpec-2048L Fiber Optic Spectrometer
has been added to the Avantes product line
since January 2009 and has many technical
specifications comparable to the standard
AvaSpec-2048. The difference is the CCD
detector, the AvaSpec-2048L uses the Sony
ILX511 detector whereas the AvaSpec-2048 uses
the ILX554B detector.
The AvaSpec-2048L is very useful for
applications where larger fiber entrance
diameter needs to be projected on the larger
CCD detector pixels of 14x200µm height.
The AvaSpec-2048L also has a better signal to noise performance and shows no peak inversion and
dark increase at the end of the detector array at longer integration times. The FWHM resolution of
the 2048L is ca 20% less good than for the standard 2048 and also non-linearity is a little less, so a
NL-calibration per channel is recommended.
All options for the AvaSpec-2048 are also available on the AvaSpec-2048L.

AvaSpec-ULS2048 Ultra Low Straylight Fiber Optic Spectrometer
AvaSpec-ULS2048
The AvaSpec-ULS2048 consists of a
revolutionary new optical bench optimized to
reduce straylight and increase both mechanical
and temperature stability. The new optical
bench has a dual internal modestripper along
with multiple CPC‟s (Compound Parabolic
Concentrators) to further reduce straylight
levels down to 0.04%, an improvement of a
factor of 2.5 over the standard AvaSpec-2048.
Along with the straylight improvement the new
optical bench design features a much higher
rigidity resulting in a factor of 10 decrease in
strain sensitivity caused by microbending and
temperature flutuations.
The new optical bench is integrated into the new AvaSpec-ULS2048, and is available for all A, B, and
C gratings and for all other options that the standard AvaSpec-2048 has
The low straylight performance of the AvaSpec-ULS2048 is extremely useful in applications where
high absorbance parameters need to be measured, such as those associated with high chemical
concentrations, high optical density optics or long optical path lengths. The new optical bench and
spectrometer are available for OEM integration in other systems as well as for purchase as individual
instruments.

The AvaSpec-3648 Fiber Optic Spectrometers is based
on the AvaBench-75 symmetrical Czerny-Turner design
with 3648 pixel CCD Detector Array. The spectrometer
has a fiber optic entrance connector (standard SMA,
others possible), collimating and focusing mirror and
diffractional grating. A choice of 16 different gratings
with different dispersion and blaze angles enable

speed interface. The AvaSpec- 3648 is especially
suitable for measuring high speed and high resolution applications, such as LIBS and pulsed light
sources. An optional detector coating can enhance the CCD performance for the UV range and a
detector collection lens offers high sensitivity.
Digital IO ports enable external triggering and control of shutter and pulsed light sources from the
Avantes line of instruments.
The new AvaSpec-3648 has a USB2 interface with fast data sampling of 270 spectra per second and
data transfer in 3.7 msec and supports analog in-and outputs as well. Optional Bluetooth (-BT)
communication and an SD card for on-board saving of spectra can be added. The AvaSpec-3648-USB2
runs on USB power and comes with AvaSoft-basic, a complete manual and USB interface cable.

AvaSpec Multichannel Fiber Optic Spectrometers
AvaSpec-4 channel in desktop
AvaSpec –USB1 platform
The AvaSpec USB1.1 platform Fiber Optic
Spectrometers can be configured as single,
dual, triple, quadruple or multi-channel
instrument with up to 8 different
spectrometer channels, all read out
simultaneously, controlled by a master´s
board microprocessor.
The simultaneous data-sampling allows fast
read-out and enables monitoring of pulsed
light sources with different channels looking
at the same pulse.
Multi-channel spectrometers all consist of the
same detector type (102/128, 256 or 1024 or 2048 pixels), the spectrometer channels can of course
cover different wavelength ranges or have different resolution specifications. For each channel
grating, wavelength range and options need to be specified.
The multi-channel spectrometers all run with one USB interface and under AvaSoft software.
Multi-channel housing can be in 9.5” desktop (for 1-4 channels) or 19” rack mount housing (1-8
channels) The pinout of the backplane connector can be found in section 2.8.1.
AvaSpec –USB2.0 platform – maximum modularity
The new AvaSpec-USB2.0 platform offers maximum modularity for multi-channel applications. For
each channel a different wavelength range, detector and integration time can be selected, without
loosing the advantage of synchronization between the different channels. The AvaSpec-USB2.0
platform uses the USB2.0 bus to connect the different channels to the PC platform and supports up
to 127 channels. New applications that can be realized with the AvaSpec-USB2.0 multi-channel
platform:
Different integration times or averaging setting per channel, still start each scan
simultaneously for all synchronized channels
Different detector types, such as UV/VIS and NIR detectors possible to cover a wide
wavelength range with one spectrometer system
More than 8 channels (even up to 127 channels) can be connected through USB2 hubs.
To order a USB2.0 multi-channel, please specify the different spectrometers (-RM) and options and
the housing (up to 4 channels in desktop, up to 10 channels in rack mount).
The spectrometer units are internally connected by a synchronization cable, which allows
simultaneous data-sampling. The synchronization enables monitoring of pulsed lightsources with
different channels looking at the same pulse.
The pinout of the backplane connector can be found in 2.9.2

AvaSpec-2048TEC Thermo-electric cooled Fiber Optic Spectrometer
AvaSpec-2048TEC
The AvaSpec-2048TEC is a special version of the
AvaSpec-2048, where the Sony 2048 CCD
detector is mounted on a one-stage Peltier
cooling device. This Peltier cooling element can
reduce the temperature of the CCD chip by ca.
30 degrees C, improving the dynamic range by at
least a factor of 10. As an additional benefit
from the cooling the dark noise is reduced by a
factor of 2-3.
The above features enable the AvaSpec-2048TEC
to be implemented in low light-level
applications, such as fluorescence and Raman
measurements, where integration times of more
than 5 seconds are needed. The AvaSpec2048TEC can be delivered as one or 2-channel instrument and has all the standard options, gratings
and specifications the normal AvaSpec-2048 has.
The AvaSpec-2048TEC is built into a desktop housing, has a cooling fan to actively ventilate the
heatsink of the Peltier cooling element and an internal power supply.

AvaSoft-Basic manual
The AvaSoft-Basic software is delivered with every Avantes spectrometer. The AvaSoft full version
software contains many additional features and applications. The full version comes with a separate
manual. Please refer to the software section in the Avantes Fiber optic Spectroscopy Catalogue for
an overview of the extra functionality in AvaSoft-Full. A detailed description about all features in
the full version can be found in the help files, or in PDF format on the AvaSpec product CD-ROM that
came with your spectrometer system.
AvaSoft-Basic 7 is available for both -USB1 and –USB2 platforms, you will find the relevant
instructions for the –USB2 platform spectrometers marked with USB2.
AvaSoft-Basic features user friendly, mouse oriented pull down menus. The mouse controls
movements of a data cursor for instantaneous readout of wavelength, pixel and y-axis magnitude.
Mouse dragging is a fast and elegant way to zoom in both x and y direction at the same time. Buttons
in the main window are available for on-line/off-line spectral analyses (start/stop), for easy saving
of reference, dark and experiment spectra, printing, changing the view to absorbance,
transmittance, irradiance or raw scope data, rescaling the y-axis and set scale for x- and y-axis.
Spectra that were saved before can be displayed graphically and compared to other saved spectra, or
to the online measured spectra. The user sets the data collection parameters, such as CCD detector
integration time, auto-dark correction, signal averaging and spectral smoothing in common dialog
boxes.

-USB1 platform
-USB2 platform
multichannel
For USB1 when AvaSoft is acquiring data, the edit fields are gray and non-editable. By clicking the
red STOP button, data acquisition is stopped and the edit fields become white and editable. The edit
bar shows the following parameters:
Integration time[ms]
This option changes the CCD readout frequency and therefore the exposure- or integration time of
the CCD detector. The longer the integration time, the more light is exposed to the detector during
a single scan, so the higher the signal. If the integration time is set too long, too much light reaches
the detector. The result is that, over some wavelength range, the signal extends the maximum
counts or in extreme case shows as a straight line at any arbitrary height, even near zero. Entering a
shorter integration time can usually solve this. Try to adjust the integration time, such that the
maximum count over the wavelength range is around 90% of the full ADC scale (14750 counts for the
14bit ADC, 59000 counts for the 16bit ADC).. When at minimum integration the signal is still too
high, an attenuator (FOA-INLINE), a neutral density filter or fibers with a smaller diameter may be
used. When not enough light reaches the spectrometer, likewise a longer integration time should be
entered.
If measurements are done in a mode in which reference and dark data are required (all modes
except Scope mode), then new reference and dark spectra need to be saved after the integration
time has been changed.
Average
With this option, the number of scans to average can be set. A spectrum will be displayed after
every # scans. This spectrum is the average of the # scans.

Wavelength[nm]
The wavelength shows the position of the cursor, which becomes visible if the cursor button is down.
The amplitude of the signal, which is given in the status bar at the bottom of the main window, is
the amplitude at the wavelength shown in this field.
Multichannel USB2 only
For multichannel USB2 spectrometers the integration time
and averaging can be set for all channels at the same value
by clicking to All.
If the dashed box is clicked, different integration time and
averaging can be set per channel .
Graphical region
The graphical region
displays the data in an
XY-diagram, with at
the X-axis the
wavelength in

Zoom features
Zoom in: select a region to be expanded to the full graph. To select this region, click the left mouse
button in the white graphical region and drag it downwards and to the right. After releasing the left
mouse button within the graphic display, both the X- and Y-axis will be rescaled to the new values of
the selected region.
Zoom out: drag with the left mouse button within the white rectangle, but in stead of dragging the
mouse downwards and to the right, drag it into another direction. After releasing the mouse button,
both the X- and Y-axis will be reset to their default values.
Move X-Y: dragging with the right mouse button results in moving the complete spectrum up or
down and to the left or right.
Move-Y: if a mouse-wheel is available on the mouse being used, then the spectrum can be moved up
or down by moving the mouse wheel.
Status bar
USB1
For each selected spectrometer channel, a statusbar at the bottom of the main window shows
information about the file to which the data will be saved, amplitude at current wavelength, and
the current settings for the smoothing and spline parameters. The field at the right of the Spline
setting is used to indicate that the spectrometer is receiving too much light at a certain wavelength
range (=16383 counts before correcting for dynamic dark, smoothing or averaging), in which case the
label “saturated” will become visible.
USB2
For each selected spectrometer channel, a statusbar at the bottom of the main window shows the
name label of the connected spectrometer channel, the file to which the data will be saved,
amplitude at current wavelength, the current settings for the smoothing and spline parameters, the
line color and style in the graphical display, the real integration time and averages per channel and
final the number of scans taken since the start button was clicked. The field at the right is used to
indicate that the spectrometer is receiving too much light at a certain wavelength range (=16383
counts for 14bit ADC, 65535 counts for 16bit ADC, before correcting for dynamic dark, smoothing or
averaging), in which case the label “saturated” will become visible.

Find peaks or valleys by CTRL or SHIFT + left mouse button click
This option can be used in all modes (Scope, Absorbance, Transmittance or Irradiance) and for all
displayed graphics. When the left mouse button is clicked in the graphical region, while the CTRL
key is down, AvaSoft will follow the following procedure to run to the closest peak:
1) The wavelength is determined from the position the mouse click occurred.
2) The data from closest pixel is retrieved
3) The direction to search for the peak is determined from the neighbor pixels. If both neighbor
pixels have a lower value at the Y-axis than the current pixel, the current pixel is already a
peak. If only one of the neighbor pixel values is higher then the current pixel value, the peak
will be searched in the direction of this higher pixel. If both neighbor pixels have a higher value
at the Y-axis than the current pixel, the current pixel is in a valley. The peak will in this case be
searched in the direction of this neighbor pixel with the highest value.
4) The cursor starts moving in the direction, as determined under 3), until it reaches a pixel of
which the value is not higher than the last one evaluated. At this pixel the cursor stops.
By holding down the SHIFT key instead of the CTRL key, the same procedure will be used to move to
the closest valley.
If more than one spectrum is being displayed, a dialog,
as shown at the right, pops up in which the spectrum
for which the peak finder needs to be activated can be
selected out of all displayed spectra.

Menu Options
In sections 3.2.1 to 3.2.4 the four main menu options (File, Setup, View and Help) and their
submenus are described in detail.
3.2.1
File Menu
File Menu: Start New Experiment
After selecting this option, a dialog box appears in which a new experiment name can be entered.
The experiment name will be saved as a filename with the extension *.kon. This extension does not
need to be entered.
After clicking the save
button, the current
filename will be built up
from the experiment name
that has been entered, and
a sequence number,
starting at 0001.
Example: if the experiment
name is “test”, the first
graphic file that will be
saved in scope mode, will
be called test0001.ROH,
the sequence number will
be automatically
incremented, so the next
file that will be saved in
scope mode will be called test0002.ROH etc. For detailed information on graphic filenames, see
File-Save Experiment. Note that the dialog allows you to select different folders or drives to save
the experiments to, as well as creating a new folder name for the new experiment. For USB1
platform the default folder in which data is saved is called “data <serialnumber>”, in which
<serialnumber> refers to the serial number of the AvaSpec spectrometer that is being used
(0208006A1 in the figure above), for USB2 platform the default directory is “data”.
After closing the dialog box by clicking the save button, the new experiment name, followed by its
sequence number, is displayed in the lower left of the status bar. By clicking the cancel button, the
old experiment name will be restored.

File Menu: Load Dark
With this option, dark data can be loaded, that have been saved before. If AvaSoft is in static mode,
the dark data that will be loaded are shown on the screen first.
File Menu: Load Reference
With this option, reference data can be loaded, that have been saved before. If AvaSoft is in static
mode, the reference data that will be loaded are shown on the screen first.
File Menu: Load Experiment
With this option, an experiment name
can be loaded, that has been used
before. This experiment name has the
file extension "*.kon". After choosing
this option, a dialog box shows all
experiments that were saved earlier
in the current experiment directory. If
the experiment name that needs to
be loaded is in this directory, select it
and click the save button. If the
experiment name that needs to be
loaded is in another drive and/or
directory, move to this
directory by clicking the
behind
the current folder name.
File Menu: Save Dark
With this option, dark data are saved. For USB1 platform the name of the dark data file is
"dark*.dat", where * represents the number of the slave channel for which the dark data has been
saved (*=0 represents the master channel). For USB2 platform the name of the dark data file is
"serialnr.drk". The dark data files will be saved in the experiment directory that has been picked by
the option File-Load-Experiment or File-Start New-Experiment.
File Menu: Save Reference
With this option, reference data are saved. For USB1 platform the name of the reference data file is
"ref*.dat", where * represents the number of the slave channel for which the reference data has
been saved (*=0 represents the master channel). For USB2 platform the name of the reference data
file is "serialnr.ref".
The reference data files will be saved in the experiment directory that has been picked by the
option File-Load-Experiment or File-Start New-Experiment.

File Menu: Save Experiment
With this option, graphic files are saved. All graphic files will be saved in the experiment directory
that has been picked by the option File-Load-Experiment or File-Start New-Experiment.
Saving graphic files if one spectrometer channel is enabled
First, a window appears in which a line of comments can be entered to the saved graph. Next two
files will be saved: the first file contains the saved spectrum data. The name of this first file starts
with the experiment name, directly followed by the sequence number of the saved spectrum. The
extension of this first file depends on the current measuring mode, as shown below:
Extension
Mode
ROH
Scope Mode
ABS
Absorbance
TRM
Transmittance/Reflectance
IRR
Irradiance
The second file contains the line of comments, which may have been added to this graph. The name
of this second file is, except for the extension, the same as the name of the first file (experiment
name and sequence number). The extension of this second file also depends on the measuring
mode, as shown below:
Extension
Mode
RCM
Scope Mode
ACM
Absorbance
TCM
Transmittance/Reflectance
ICM
Irradiance
Example: suppose the name of our experiment is "avantes". Then, saving one spectrum in scope
mode, one in absorbance mode and two in transmittance mode results in the following files:
avantes0001.roh:
spectrum data in scope mode
avantes0001.rcm:
comments for the spectrum saved in avantes0001.roh
avantes0001.abs:
spectrum data in absorbance mode
avantes0001.acm:
comments for the spectrum saved in avantes0001.abs
avantes0001.trm:
spectrum transmittance mode
avantes0001.tcm:
comments for the spectrum saved in avantes0001.trm
avantes0002.trm:
spectrum data in transmittance mode
avantes0002.tcm:
comments for the spectrum saved in avantes0002.trm

After leaving the application and opening AvaSoft the next time, saving graphics in scope,
absorbance and transmittance mode, will then result in respectively the data-files avantes0002.roh,
avantes0002.abs and avantes0003.trm, as well as the comment files avantes0002.rcm,
avantes0002.acm and avantes0003.tcm.
Before saving, the name of the graphic file is displayed in the status bar at the bottom of the
screen. After saving, the sequence number is automatically incremented by one.
Saving graphic files if multiple spectrometer channels have been enabled
If graphic files are saved while more than one channel is enabled at the same time (see option ViewChannel), then the graphic filename for each channel that is displayed gets a different sequence
number. For example, the result of saving one experiment in triple view mode is three graphic data
files and three comment files, for instance:
avantes0002.roh: spectrum data in scope mode (e.g. spectrometer 1 or Master)
avantes0003.roh: spectrum data in scope mode (e.g. spectrometer 2 or Slave1)
avantes0004.roh: spectrum data in scope mode (e.g. spectrometer 3 or Slave 2)
avantes0002.rcm: comments for the spectrum saved in avantes0002.roh
avantes0003.rcm: comments for the spectrum saved in avantes0003.roh
avantes0004.rcm: comments for the spectrum saved in avantes0004.roh
For each channel a different comment line can be entered.
To make it easier to select the graphic files later on with the option File-Display Saved Graph, all
comment lines start with a short name for the channel at which the graph has been saved: M for
Master, S1 for Slave1 and so on.
After saving, the sequence numbers in this example (triple view mode) will automatically have been
increased to 0005, 0006 and 0007, for resp. Master, Slave1 and Slave2.
File Menu: Print
After selecting the print menu option, the background colors in the graphical region will become
white. If the menu option “Black and
White printer” (see next section) has
been marked, the line style for the
spectra will also change from colored
to black. A dialog will be shown in
which the title for the printout can
be entered. In the next window, the
printer settings can be changed (e.g.
portrait or landscape printing,
printing quality etc.). After clicking
OK in the printer settings dialog, the
graph will be printed, and the
original graph colors will be restored
on the monitor.

File Menu: Black and White printer
The default setting in AvaSoft is to print the spectra in the same color as they appear on the
monitor. However, if a color printer is not available, the menu option “Black and White printer” can
be enabled. If this option is enabled, different line styles will be printed if more than one spectrum
is displayed, e.g. dash-dash, dot-dot, dash-dot. To enable this option, click the menu option and a
checkmark appears in front of it.
File Menu: Display Saved Graph
This option requires that graphic files
were saved earlier by using the option
File-Save Experiment. After choosing this
option or clicking with the right mouse
button on the legenda in the display
window, a window shows all files in the
current measure mode. In the example at
the right, the measure mode is “scope”,
so the extension of the earlier saved
spectra is *.roh.
To select graphic files that were saved in
another measure mode, e.g. absorbance,
click
behind the Graph - …Mode, and
pick the desired measure mode.
To select graphic files from another folder or drive, click
behind the current folder name.
If a graphic file is marked by a (single) mouse click on the filename, the comment line for this file
appears at the top of the graphical region in the main window. Selecting multiple filenames can be
realized by using the CTRL or SHIFT key in combination with the mouse. If the CTRL key is pressed,
all the files that are clicked by the mouse will be selected for displaying. If the SHIFT key is pressed,
all the files in between two
clicked files will be selected for
displaying.
Select the name of the file(s) to
be displayed and click the Open
button. To leave this dialog
without displaying graphic files,
click the CANCEL button.
In the figure at the right, two
graphic files were selected in
scope mode. The comments that
were saved with these graphs are
displayed at the top of the
graphical region, together with
information about amplitude at
current wavelength (amp),
integration time (it) and
smoothing (s) settings at
the moment that the file was saved and the name of the graphic file. If the active spectrometer
channels (e.g. Master) have not been unselected with the View Channel option, the actual data for
the activated channel(s) will be displayed in the same graph as the selected graphic files. By clicking

Setup Menu
Setup Menu: Hardware
USB1 platform
This menu option displays a list of AvaSpec serial numbers that are connected to the PC‟s USB
port(s) and COM port(s) and which are not used by another (instance of the) application. This option
can be used to allocate a spectrometer to an application (for example if one spectrometer is running
with AvaSoft-Basic and another spectrometer needs to run with AvaSoft-Raman software). But it can
also be used to run multiple spectrometers simultaneously, just by restarting AvaSoft multiple times.
After clicking the OK button, AvaSoft will communicate with the spectrometer serial number that
has been activated in the dialog.
USB2 platform
This option shows all connected spectrometers and allows you to change the name of the channel
and to deactivate and activate spectrometers. For synchronization of scans a master sync
spectrometer needs to be dedicated, in Multichannel platforms usually the spectrometer from the
left as seen from the front is prededicated as master sync by Avantes.
AvaSpec-3648-USB only
The Toshiba detector, as implemented in the AvaSpec-3648, can be used in 2 different control
modes:
1. The Prescan mode (default mode).
Apr-09
Avantes
67
www.avantes.com
[email protected]
In this mode the Toshiba detector will generate automatically an additional prescan for
every request from the PC, the first scan contains non-linear data and will be rejected, the
2nd scan contains linear data and will be showed on the screen and/or saved. This prescan
mode is default and should be used in most applications, like with averaging (only one
prescan is generated for a nr of averages), with the use of an AvaLight-XE (one or more
flashes per scan) and with multichannel spectrometers. The advantage of this mode is a very
stable and linear spectrum. The disadvantage of this mode is that a minor (<5%) image of the
previous scan (ghostspectrum) is included in the signal.
This mode cannot be used for fast external trigger and accurate timing, since the start of
the scan is always delayed with the integration time (min. 3.7 ms).
2. The Clear-Buffer mode.
In this mode the Toshiba detector buffer will be cleared, before a scan is taken. This clearbuffer mode should be used when timing is important, like with fast external triggering. The
advantage of this mode is that a scan will start at the time of an external trigger, the
disadvantage of this mode is that after clearing the buffer, the dector will have a minor
threshold, in which small signals (<500 counts) will not appear and with different integration
times the detector is not linear.
Setup Menu: Wavelength Calibration Coefficients
After clicking this option, a dialog is shown in which the wavelength calibration coefficients can be
changed manually and start/stoppixels can be set to speed up datatransfer.
Background
The wavelength that corresponds to a pixel number (pixnr) in the detector in the spectrometer can
be calculated by the following equation:
= Intercept + X1*pixnr + X2*pixnr2 + X3*pixnr3 + X4*pixnr4
in which Intercept and X1 to X4 correspond to Intercept and First to Fourth Coefficient in the figure
below.
For example, if we want to calculate the wavelength at pixel number 1000, using the numbers in the
figure at the right, the wavelength becomes:
=
384,054 + 0,136492*1000 +
-6,71259E-6*1E6 +
-5,66234E-10*1E9
=
513,267 nm.
The „Restore Factory Settings‟ button
restores for all spectrometer channels the
original wavelength calibration coefficients
that were saved to the EEPROM during
factory calibration.
The “Process data only when in following
wavelength range” option can be used to
transfer only a limited number of pixels
from the spectrometer to the PC. This can significantly speed up the transfer time (e.g. for the
AvaSpec-2048 from 30 ms at full wavelength down to 14 ms for a small selection of 10 pixels). A
second advantage is data reduction, because only the spectral data will be saved at the pixels for
which the wavelength is in the specified wavelength range.

Setup Menu: Smoothing and Spline
The Cubic Spline Interpolation Algorithm can be
applied to get a better estimation for the spectral data
between the pixels on the detector array.
Smoothing is a procedure, which averages the spectral
data over a number of pixels on the detector array.
For example, if the smoothing parameter is set to 2,
the spectral data for all pixels xn on the detector array
will be averaged with their neighbor pixels xn-2, xn-1,
xn+1 and xn+2.
Cubic Spline Interpolation
In the figure at the right, the
effect of spline interpolation is
illustrated. The Master data shows
the AD counts for 4 pixels,
connected by a straight line
(linear interpolation). The Slave1
data is for these 4 pixels exactly
the same as for the Master data,
but this time the cubic spline
interpolation algorithm has been
applied, resulting in data which is
smooth in the first derivative and
continuous in the second
derivative.
The spline interpolation can be
useful for applications in which
the output of line sources, like
laser diodes is displayed, or for
other applications, which require a high resolution. Note that for the AvaSpec-2048 with 2048 pixels,
the effect of spline interpolation is not visible if the data is shown at full scale. The monitor
resolution is much less than 2048 pixels. The effect of spline interpolation can only be visualized if
the number of detector pixels that are displayed is smaller than the number of monitor pixels at the
x-axis.
Smoothing
To get a smoother spectrum without losing information it is important to set in the software the
right smoothing parameter. The optimal smoothing parameter depends on the distance between the
pixels at the detector array and the light beam that enters the spectrometer. For the AvaSpec-2048,
the distance between the pixels on the CCD-array is 14 micron.
With a 200 micron fiber (no slit installed) connected, the optical pixel resolution is about 14.3 CCDpixels. With a smoothing parameter set to 7, each pixel will be averaged with 7 left and 7 right
neighbor pixels. Averaging over 15 pixels with a pitch distance between the CCD pixels of 14 micron
will cover 15*14 = 210 micron at the CCD array. Using a fiber diameter of 200 micron means that we
will lose resolution when setting the smoothing parameter to 7. Theoretically the optimal smoothing
parameter is therefore 6.
The formula is ((slit size/pixel size) – 1)/2
In the table below, the recommended smoothing values for the AvaSpecs spectrometer are listed as
function of the light beam that enters the spectrometer. This light beam is the fiber core diameter,
or if a smaller slit has been installed in the spectrometer, the slit width. Note that this table shows
Apr-09
Avantes

the optimal smoothing without losing resolution. If resolution is not an important issue, a higher
smoothing parameter can be set to decrease noise against the price of less resolution.

Setup Menu: Use 16bit ADC in 14bit mode (only USB2 platform, HW rev 1D and later)
The 14bit AD Converter used with the as5216 boards revision 1B and 1C inside the AvaSpec-USB2 has
been replaced by a 16bit ADC since the release of the as5216 board revision 1D. Therefore, the
default range in Scope Mode for an AvaSpec-USB2 has changed from a 14bit range (0..16383) to 16bit
(0..65535).
If the menu option “Use 16bit ADC in 14bit mode” is enabled (preceded by a checkmark), the 16bit
range AD Counts will be converted to a 14bit range by the as5216.dll (divide by 4.0). This option has
been added for customers who have been already working with earlier versions of the AvaSpec-USB2
with 14bit ADC, and want to be able to compare the data in scope mode between both
spectrometers. Note that by setting the 16bit ADC into 14bit mode, you will not loose resolution
because the numbers are not truncated or rounded to integer numbers, e.g. 5 counts in 16bit mode
will become 1.25 counts in 14-bit mode.
If multiple AvaSpec-USB2 spectrometers are connected simultaneously and one or more devices
don‟t support the 16bit ADC (rev 1B or rev 1C as5216 board), all spectrometers will be set
automatically into 14bit mode (range 0..16383 AD counts).
Setup Menu: Correct for Dynamic Dark (AvaSpec-2048/3648 only)
The pixels of the CCD detector (AvaSpec-2048/3648/2048x14) are thermally sensitive, which causes
a small dark current, even without light exposure. To get an approximation of this dark current, the
signal of the first 14 optical black pixels of the CCD-detector can be taken and subtracted from the
raw scope data. This will happen if the correct for dynamic dark option is enabled. As these 14
pixels have the same thermal behavior as the active pixels, the correction is dynamic.
Note that this option is different from the dark current that needs to be saved before any
transmittance or absorbance measurements can be taken (File-Save Dark). If the correct for dynamic
70
Avantes

dark option has been changed, it will be necessary to save a new dark and reference spectrum
because the raw data has been changed.
If this menu option is preceded by a checkmark, the scope data is corrected with the dynamic dark
algorithm. It is recommended to leave this setting checked, which is the default state.
Setup Menu: Subtract Saved Dark
This option is used to subtract the dark spectrum that has been saved (File-Save Dark) from the raw
scope data. After starting up AvaSoft, this menu option is always unselected, because a dark
spectrum needs to be saved or loaded before it can be subtracted.
If this menu option is preceded by a checkmark, the scope data is corrected with the saved dark.
Setup Menu: Strobe Enable
This option can be used to enable or disable an external strobe (e.g. the AvaLight-XE) attached to an
AvaSpec spectrometer. The measured light intensity of the AVALIGHT-XE is independent of the
integration time in AvaSoft. To increase light intensity, the number of pulses per integration interval
should be increased. The maximum frequency at which the AVALIGHT-XE operates is 100 Hz. This
means that the minimum integration time for 1 pulse per scan is 10 ms. When setting the number of
pulses e.g. to 3, the minimum integration time becomes 30 ms. It is recommended to keep the
integration time as low as possible to avoid unnecessary increase of noise.
USB1 platform
The AvaLight-XE needs to be attached to the AvaSpec by connecting an IC-DB15-2 interface cable to
the high density 15 pole Sub-D connectors at the AvaSpec and AvaLight -XE. If used with an old XE2000, the XE-2000 has the possibility to switch between Single Flash and Multi Flash (in that case
there will be a switch at the backside of the XE2000), make sure that the switch is always in the
Single Flash position, when using the XE-2000 with an
AvaSpec spectrometer (in Single Flash mode the XE2000 is triggered at pin 1, in Multi Flash mode at pin
2). When clicking the “Strobe Enable” menu option, a
dialog is shown in which this number of pulses can be
set.If this menu option is preceded by a checkmark,
the strobe control function has been enabled. To
disable the strobe, simply click the menu option when
preceded by a checkmark.
Strobe (AvaLight-XE) Control USB2 platform
The AvaLight-XE needs to be attached to AvaSpec-USB2 by connecting
an IC-DB26-2 interface cable between the high density 26 pole Sub-D
connectors at the AvaSpec-USB2 and the 15-pole DB connector of the
AvaLight -XE. If used with a multichannel system, make sure that the
AvaLight-XE is connected to the master sync spectrometer, only the
number of flashes per scan set for the master synch spectrometer will
determine flash rate. To disable the strobe, simply enter 0 under the
NrOfFlashes.

Start the AvaSoft software, and click the Start button in the main window.
Connect a fiber to the Spectrometer input port.
Adjust the Smoothing Parameters in the Setup menu to optimize smoothing for the Fiber/Slit
diameter that is used.
Set up the experiment such that the other end of the fiber points at the sample of light to be
determined (use a fixture for the best results). Usually some sort of spectrum may be seen on
the screen, but it is possible that too much or too little light reaches the spectrometer at the
present data collection settings. Too much light means that, over a certain wavelength range,
the signal is overloaded shown as a straight line at any arbitrary height, even near zero. This
can usually be solved by a shorter integration time. The integration time can be changed in
the main window, in the white box below the start/stop button. If AvaSoft is collecting data,
the start/stop button shows a red „stop‟ and the integration time box is gray, indicating that
it cannot be changed. After clicking the „stop‟ button the data acquisition stops and the
integration time can be changed. The result of the changed integration time can be viewed
after clicking the green „start‟ button. Try to adjust the integration time, such that the
maximum count over the wavelength range is around 90% of the full ADC scale (14750 counts
for the 14bit ADC, 59000 counts for the 16bit ADC). When at minimum integration the signal is
still too high, fibers with a smaller diameter can be used. When not enough light reaches the
spectrometer, likewise a longer integration time should be entered.
When a good spectrum is displayed, turn off the light source.
Now save the Dark data. This is done by File-Save Dark from the menu or by clicking the black
square on the left top of the screen with the mouse.
Turn on the reference light source of known color temperature (2850K for AvaLight-HAL
with default jumper setting) and set up the fiber end that is not connected to the
spectrometer, so that a good spectrum is displayed on the screen. Note that the integration
time or fiber type may not be changed while measuring the reference data. If there is too
much light, adjust the focusing of the light source, so less light is coupled into the fiber. As
long as only light from the reference light source and no ambient light is coupled into the
fiber, this will not influence the spectral distribution, only its height. Try to set up the fiber
such that the maximum count over the wavelength range is around 90% of the full ADC scale
(14750 counts for the 14bit ADC, 59000 counts for the 16bit ADC).
Save the Reference data. This is done by File-Save Reference from the menu or by clicking the
white square on the left top of the screen with the mouse.
Note that the whole operation of saving a reference file does not need to be carried out each
time a new experiment is started. The reference data are saved in a file called ref*.dat and
can be loaded next time by choosing the option File-Load Reference. After saving or loading
reference and dark the irradiance mode can be chosen by clicking the „I‟ button or by the
menu option View-Irradiance mode. First a message box appears in which the value of the
color temperature in Kelvin of the light source that has been used as a reference can be
entered. If light from the reference light source is viewed, the Planck-curve for the color
temperature of the reference light source is displayed, as shown in the figure on the next
page. The maximum of the reference Planck-curve has been set to 100.

Plug in the connector of the power supply into the socket of AvaLight-HAL-CAL.
Connect the SMA-connector of your fiber to the SMA-plug of the CC-UV/VIS
Switch on the Halogen lamp with the frontside switch.
Changing of the bulb
Since the light source is calibrated, the bulb exchange and recalibration can only be done in our
calibration lab.
N.B. The AvaLight-HAL-CAL cannot be used as a light source for standard reflection/absorption
spectroscopy.
How to take absolute irradiance measurements with AvaSoft 7 full
1. Start the AvaSoft 7 software, and click the Start button in the main window.
2. Connect a fiber to the Spectrometer input port.
3. Start the Absolute Irradiance Application software by clicking the menu option:
Application/Absolute Irradiance. Click the “Perform Intensity Calibration” button.
4. Select the spectrometer channel that will be calibrated, the calibration lamp file and enter the
diameter of the fiber/cosine corrector or integrating sphere sample port that is used.
5. Turn on the reference light source (e.g. AvaLight-HAL-CAL or AvaLight-HAL-CAL-ISP). If a cosine
corrector is used at the end of the fiber, mount it directly on the reference light source. If an
integrating sphere is used at the end of the fiber, put the integrating sphere sample port over
the light output port.
6. Verify that the calibration lamp is ON for at least 15 minutes, and click the “Start Intensity
Calibration” button. Try to adjust the integration time while looking at the reference light, such
that the maximum count over the wavelength range is around 14000 counts. It‟s also possible to
let AvaSoft search for an optimal integration time by clicking the „ AC‟ button.
7. Adjust the Smoothing Parameter to optimize smoothing for the Fiber/Slit diameter that is used.
8. If a good reference signal is displayed, click the white “Save Reference” button. A white line
will mark the reference spectrum. Then switch off the calibration lamp, wait until the spectrum
becomes flat, near the bottom of the scale, and click the black button to save a dark spectrum.
A black line will mark the dark spectrum.
9. Click the “Save Calibration” button. A dialog shows up in which the current settings in this
intensity calibration are shown. If the calibration has been performed with diffuser, the
intensity calibration data will be saved to an ASCII file with extension *.dfr, with bare fiber this
Apr-09

[email protected]
extension will be *.fbr. The name of the intensity calibration file can be entered after clicking
the “Save As” button.
10. Switch to the Irradiance Chart TAB to enter the hardware setup and select the colorimetric,
radiometric, photometric and/or peak parameters of interest. Then click OK.
11. Measure the output parameters in the experiment. If needed, change the integration time, such
that the maximum in Scope Mode is around 14000 A/D Counts . Block the light path to the
spectrometer, and save a dark spectrum. If the (ir)radiance of the light to be measured needs to
be displayed against time, click the time measurement TAB in the settings dialog as described in
section 4.4.6.
12. The intensity calibration as performed under point 9 can be loaded in future experiments by
selecting the option “Load Intensity Calibration”, as described below under Quick Start (2).
After loading an intensity calibration, a dark spectrum needs to be saved before switching to
Irradiance mode.

AvaLight-DH-CAL UV/VIS calibrated light source
The AvaLight-DH-CAL is a calibrated light source for the UV/VIS/NIR spectral range (200-1099nm).
Optionally an extended calibration for the NIR spectral range (1100-2500 nm) can be ordered. This
NIST-traceable calibrated light source is developed for use with all AvaSpec spectrometers to be
used in measuring absolute spectral intensity.
The AvaLight-DH-CAL comes with a cosine corrector with SMA adapter. The software includes two
calibration files, both valid for calibration with the cosine corrector. One calibration file can be used
for irradiance calibration over the full range (200-1099nm). In that case the Deuterium and Halogen
light need to be switched on during the calibration. The other calibration file can be used for
irradiance calibration over the VIS/NIR range (350-1095nm). In that case only the Halogen light
needs to be switched on which gives a more smooth and stable output at the higher wavelengths.
Optionally an extended calibration for the NIR spectral range (1100-2500 nm) can be supplied.
The calibration files can be imported in the AvaSoft-IRRAD application software, developed to make
your spectrometer system a spectroradiometer.
Changing of the bulb
Since the light source is calibrated, the bulb exchange and recalibration can only be done in our
calibration lab.
N.B. The AvaLight-DH-CAL cannot be used as a light source for standard reflection/absorption
spectroscopy.
How to take absolute irradiance measurements with AvaSoft 7-IRRAD
1. Start the AvaSoft 7 software, and click the Start button in the main window.
2. Connect a fiber to the Spectrometer input port.
3. Start the Absolute Irradiance Application software by clicking the menu option:
Application/Absolute Irradiance. Click the “Perform Intensity Calibration” button.
4. Select the spectrometer channel that will be calibrated, the calibration lamp file and enter
the diameter of the fiber/cosine corrector or integrating sphere sample port that is used.
5. Turn on the reference light source (e.g. AvaLight-DH-CAL or AvaLight-DH-CAL-ISP). If a cosine
corrector is used at the end of the fiber, mount it directly on the reference light source. If an
integrating sphere is used at the end of the fiber, put the integrating sphere sample port over
the light output port.
6. Verify that the calibration lamp is ON for at least 15 minutes, and click the “Start Intensity
Calibration” button. Try to adjust the integration time while looking at the reference light,
such that the maximum count over the wavelength range is around 14000 counts. It‟s also
possible to let AvaSoft search for an optimal integration time by clicking the „ AC‟ button.
7. Adjust the Smoothing Parameter to optimize smoothing for the Fiber/Slit diameter that is
used.
8. If a good reference signal is displayed, click the white “Save Reference” button. A white line
will mark the reference spectrum. Then switch off the calibration lamp, wait until the
spectrum becomes flat, near the bottom of the scale, and click the black button to save a
dark spectrum. A black line will mark the dark spectrum.
9. Click the “Save Intensity Calibration” button. A dialog shows up in which the current settings
in this intensity calibration are shown. If the calibration has been performed with diffuser,
Apr-09
Avantes
101
www.avantes.com
[email protected]
the intensity calibration data will be saved to an ASCII file with extension *.dfr, with bare
fiber this extension will be *.fbr. The name of the intensity calibration file can be entered
after clicking the “Save As” button.
10. Switch to the Irradiance Chart TAB to enter the hardware setup and select the colorimetric,
radiometric, photometric and/or peak parameters of interest. Then click OK.
11. Measure the output parameters in the experiment. If needed, change the integration time,
such that the maximum in Scope Mode is around 14000 A/D Counts . Block the light path to
the spectrometer, and save a dark spectrum. If the (ir)radiance of the light to be measured
needs to be displayed against time, click the time measurement TAB in the settings dialog.
12. The intensity calibration as performed under point 9 can be loaded in future experiments by
selecting the option “Load Intensity Calibration”, as described below under Quick Start (2).
After loading an intensity calibration, a dark spectrum needs to be saved before switching to
Irradiance mode.

Fiber optics
General Information
Core
For existing sensor applications, generally, multi-mode step index silica fibers are used. These
range in core thickness from 50 microns to 1 mm. The core is made out of pure silica. Other fiber
cores with much higher absorption are made out of certain glass types or plastics. These are not
offered in this catalog.
First a distinction is made between silica with high or low OH content. Silica fibers with high OH
(600-1000 PPM) are used in the UV/VIS wavelength range because of the low absorption in the UV.
They are referred to as UV/VIS fibers. For Deep-UV applications special solarization resistant fibers
can be used.
The OH content causes strong absorption peaks in the NIR wavelength range. In order to get good
fibers for the NIR range, the "water" is removed from the silica. This results in low OH fibers (<2 PPM
) with low absorption in the NIR. They are referred to as VIS/NIR fibers.
Cladding
In order to get the light guiding effect the core is cladded with a lower index of refraction material.
For the highest quality fibers with the lowest absorption this is a fluorine-doped silica, the so-called
silica-silica or all-silica fibers with a numerical aperture (NA) of 0.22.
Buffers
Without further protection fibers would easily break, because of small scratches or other
irregularities on the surface. Therefore a next layer, the buffer, is added. This buffer also
determines under what circumstances the fiber can be used. Temperature range, radiation, vacuum,
chemical environment and bending are factors to be considered.
Polyimide buffers offer a wide temperature range (-100 to 400 C) and superior solvent resistance.
Also, this material is non-flammable. Drawbacks are sensitivity to micro bending and the difficulty
to remove it.
For extreme temperatures (-190 to 750 C) a gold buffer is used. Gold-coated fibers are virtually
inert to all environments and make hermetically sealed high pressure feed trough's possible. (See:
pressure feed troughs). The same is true for aluminum buffers for temperatures from -190 up to
about 500 C. Low out gassing makes them also excellent for use in vacuum.

UV/VIS Fiber attenuation
VIS/NIR Fiber Attenuation
Solarization Resistant Fibers for Deep UV applications
Most spectroscopic applications with fiber optics have been restricted to wavelength ranges above
230nm, because standard silica fibers with an undoped core and fluorine doped cladding are
frequently damaged by exposure to deep-UV light (below 230nm). This solarization effect is induced
by the formation of "color centers" with an absorbance band of 214 nm. These color centers are
formed when impurities (like Cl) exist in the core fiber material and form unbound electron pairs on
the Si atom, which are affected by the deep UV radiation.
Not long ago, solarization resistant fibers, which were hydrogen loaded, were developed (UVI). The
disadvantage for these fibers is the limitation on smaller fiber diameters and limited lifetime,
caused by the H2 outgass from the fiber.
Recently, with the availability of a modified core preform, a new fiber became available (UVM). This
fiber provides long-term stability at 30-40% transmission (for 215nm). All fiber optic probes, cables
and bundles with core diameters of 100µm, 200m, 400m and 600µm can be delivered with
solarization resistant fibers. All assemblies, made by us, are pre-solarized for an 8-hrs period, to
have a constant transmission of 30-40% @ 215nm.

Fiber optic cables
Fiber optic cables can be made in different lengths with different type of connectors, like SMA905,
ST or FC-PC connectors. The fibers are also available in different wavelength regions, like Deep UV
solarization resistant fibers, UV/VIS fibers and VIS/NIR fibers.
We offer different shielding, like Kevlar reinforced PVC sleeving with PTFE inner tubing (standard) or
metal shielding with silicon or PTFE inner tubing for higher temperature and more industrial
applications.
Depending on the intended wavelength range a UV/VIS (200-750 nm) or a VIS/NIR (500-1000 nm)
fiber is used. In the following table replace xx by respectively UV or IR. For deep UV use specify –SR
(solarization resistant).
5.2.1
Patch cords
Patch cords are standard delivered in 2m length with SMA-905 terminations. One side of each patch
cord fiber has an extended ferrule in order to allow easily connecting into the AvaSpec
spectrometers optical bench.
Please follow the next rules:
1. Gently remove the plastic protection caps from the fiber SMA connectors.
2. Inspect the fibers if light is transmitted, note that for small fiber diameters the transmitted light
energy may be low, so it is hard to see.
3. Do not bend the fiber too tightly, the minimum recommended bending radius of a fiber is 600
times the core/cladding diameter (i.e. 12 cm for a 200µm fiber), further bending may induce
losses in optical transmittance. Bending the fiber below a radius of 200 times the fiber diameter
may cause irreversible damage.
4. Keep connectors and tips protected by the plastic caps when not in use.
5. When necessary the fiber end can be cleaned with soft tissue and alcohol or acetone, avoid
scratching.
6. Do not exceed temperature specifications.

3. Optical inspection of scratches on the surface.
4. A Deep-UV burn-in of 8 hours to pre-solarize the -SR assemblies, the attenuation at 215nm is
registered.
5. There is always a label attached to the fiber optic cable or assembly that will tell you the serial

Bending
Minimum bend radius: Short term (few seconds) 20 mm, long term: 60 mm
Please follow the next rules:
1. Gently remove the plastic protection caps from the fiber SMA connectors.
2. Inspect the fibers if light is transmitted, note that for small fiber diameters the transmitted light
energy may be low, so it is hard to see.
3. Do not bend the fiber too tightly, the minimum recommended bending radius of a fiber is 600
times the core/cladding diameter (i.e. 12 cm for a 200µm fiber), further bending may induce
losses in optical transmittance. Bending the fiber below a radius of 200 times the fiber diameter
may cause irreversible damage.
4. Keep connectors and tips protected by the plastic caps when not in use.
5. When necessary the fiber end can be cleaned with soft tissue and alcohol or acetone, avoid
scratching.
6. With the probe a 1,5mm wrench allyn key is delivered, so the setscrew of the variable path can
be loosened, before changing the path length. Afterwards the setscrew needs to be tightened.
7. Since the optical reflector at the end of the probe is a diffuse reflecting material, a calibration
of absorption values versus concentration needs to be done for all the chosen path lengths.
8. Do not exceed temperature specifications.

In our standard quality assurance procedure, each fiber optic assembly is labeled with a serial nr,
and some standard test are being carried out with a spectrometer and AvaLight-CAL Line source and
registered:
1. Spectral attenuation at 253 nm for UV/VIS fibers, spectral attenuation at 763 nm for VIS/NIR
fibers.
2. Symmetries of the connector for both sides; the maximal peak value is allowed to move as many
nm as the registered resolution of the fiber / spectrometer.
3. Optical inspection of scratches on the surface.
4. A Deep-UV burn-in of 8 hours to pre-solarize the -SR assemblies, the attenuation at 215nm is
registered.
There is always a label attached to the fiber optic Dip probe that will tell you the serial nr, so the
QA data can be retraced.

Collimating lenses
The COL-UV/VIS collimating lenses screw onto the end of an SMA fiber and convert the divergent
beam of radiation light into a parallel beam. Collimating lenses can be used in any optical setup that
requires parallel beams of light at the illumination source or at the entrance optics or at both sides.
The COL-UV/VIS-90 is used to focus the exit light under 90 °.
Standard optical fibers have a n.a. of 0.22, which is an acceptance angle of 25°. The collimating
lenses are adjustable, providing an acceptance angle of near 0° to about 3°.
The FCR-COL is used to collimate the light of a standard ¼” ferrule reflection probe, the FCR-COL
also has an adjustable focus.
Please follow the below instructions to adjust the focus of your collimating lens:
1. Connect the fiber between the collimating lens and the light source.
2. Turn on the light source and focus the light in a white paper in ca. 100 mm distance.
3. Loosen the setscrew with the Allen Wrench key 1.27 mm on the barrel and slide the inner barrel
until you see a sharp focused spot without light intensity and color variations across the beam
spot.
4. Tighten the setscrew with the Allen Wrench key 1.27 mm.

Cosine corrector
The cosine correctors are spectro radiometric sampling optics, designed to collect radiation (light)
over 180°, thus eliminating optical interface problems associated with the light collection sampling
geometry inherent to other sampling devices.
The CC-UV/VIS cosine corrector has teflon diffusing material and is optimized for applications from
200-1100 nm. For the VIS/NIR range (350-2500nm) a Radin material is available in the CC-VIS/NIR.
Both cosine correctors screws onto the end of any SMA-terminated optical fiber. When coupled to a
miniature fiber optic spectrometer, these cosine correctors can be used to measure UV-A and UV-B
solar radiation, environmental light, lamps and other emission sources.
The Cosine Correctors have a 0.25" O.D. barrel with a smooth yet rugged black oxyde finish. The
diffusing material is a thin disk that fits at the end of the barrel. The cosine corrector has an SMA
905 connector for convenient coupling to optical fibers.

Reflection probe Holder
The Reflection probe holder is to fix a FCR standard reflection probe under an angle of 90 or 45
degrees, the holes have a 6,5 mm diameter and contain a setscrew to fix the probe in its position.
The RPH measures 60 x 30 x 30 mm.
The reflection probe holder was developed for 2 types of reflection, specular and diffuse:
1. Specular reflection: Put the probe in the 90° aperture, adjust the distance from the
measurement surface and tighten the setscrew with the 1.5 mm Allyn Wrench. Connect the 6fiber leg to the light source and the read fiber to the spectrometer.
2. Diffuse reflection (for color measurements) : Put the probe in the 45° aperture, adjust the
distance from the measurement surface and tighten the setscrew with the 1.5 mm Allyn Wrench.

Integrating spheres
The AvaSphere integrating sphere family can be delivered with an active diameter of 30, 50 or 80
mm (XX means the active diameter) and an SMA port at 90 degrees for both irradiance and reflection
measurements, the reflection sphere has an additional SMA- connector port at 8 degrees. Both
versions have a sample port diameter of 6 mm for the 30 mm diameter sphere, 10 mm for the 50
mm diameter sphere and 15 mm for the 80 mm diameter sphere. The irradiance version of the
integrating sphere can be used to measure light sources (Laser, LED, and Halogen Lamps). The
reflection version is used to measure reflective surfaces, as well as for color measurement and
fluorescence spectroscopy. A light source may be connected to SMA-connector port through a fiber
optic bundle to make the integrating sphere an ideal uniform light source. The integrating sphere is
made out of highly reflective diffuse material, its surface is reflecting the light diffuse with more
then 95% in the spectral range from 250-2500 nm.
Operating instructions for the irradiance spheres
1. Connect an optical fiber between the SMA terminated measurement port of the sphere and the
spectrometer.
2. Insert your emission source (Laser, LED, and Halogen Lamps, or light fiber) into the sphere
sample port .
3. To collect diffuse radiation (light) from a 180° field of view, eliminating direct light collection
by the detection fiber a baffle is installed in the sphere.
4. Measurements should be done in AvaSoft's relative or absolute irradiance mode, see the
appropriate documentation.
Operating instructions for the reflection spheres
Since the reflection sphere has 2 SMA ports, one under 8° and one under 90°, the sphere can be
connected for reflection measurements in 2 ways:
1. Direct illumination, indirect measurement or
2. Indirect illumination and direct measurement
We always recommend to use the first method of directly illuminating and indirect measurement.
This method has the advantage that the white light of the source directly illuminates the object.
The diffuse and specular reflection is indirectly measured by the sample port. In the second method
the illumination is indirect and therefore the object surface becomes a part of the sphere, so the
illumination of the object is actually not white light anymore, depending on the color of the object.
Such method requires a second spectrometer channel to measure the illumination in the sphere.
The operating instructions refer to the first method of direct illumination and indirect measurement:
118
Avantes
Apr-09
www.avantes.com
[email protected]
1. Connect an optical read fiber between the SMA terminated measurement port on the side of the
sphere and the spectrometer.
2. Connect an optical illumination fiber or bundle between the SMA terminated illumination port
on the top of the sphere and the light source. We recommend a 600um fiber or a bundle of 7
fibers of 200um. A bigger bundle will result in a collimated measurement spot, which is bigger
than the sample port and will therefore make the measurement less accurate.
3. Loosen the set screw of the collimating lens with the Allen Wrench key 1,27 mm on the barrel
and slide the inner barrel until you see a sharp focused spot without light intensity and color
variations across the beam spot. Focus the illumination spot on the sample port, the optimal
focusing point diameter is ca. 80% of the sample port diameter. The best way to see the spot is
to put a white paper on the sample port and hold the sphere upside down.
4. Now you can put your AvaSphere on the object you would like to measure, do not forget to take
dark and reference (on a WS-2 white tile) first.
5. The maximum angle of diffuse reflection is 120° field of view.
6. Measurements should be done in AvaSoft's reflectance or color parameter mode, see the
appropriate documentation.

WS-2 White reflective tile
The WS-2 white reference tile is made out of a white diffuse plastic material, meeting the highest
demands with regard to high grade diffuse reflectance, mostly used in colorimetry applications
where a reference signal has to be obtained during a reflection measurement. Thanks to most
accurate preparation of the PTFE and its processing to an amorphous structure, the tile reflects light
from 350-1800 nm with ca 98% and from 250-2500nm more than 92%. The material offers along term
stability, even in deep UV applications, the plastic is hydrophobic and chemically inert.
The material can be delivered as custom designed items, such as the WS-2-GEM with a 10 mm radius
hole for nitrogen cooling of gemstones for gemology applications, contact us for more information.
General Care
WS-2 is an optical standard and should be handled in much the same way as other optical standards.
Although the material is very durable, care should be taken to prevent contaminants such as finger
oils from contacting the material‟s surface, because this causes a loss of reflectivity especially in
the UV region. Always wear clean gloves when handling WS-2!
Cleaning Instructions
If the material is lightly soiled, it may be air brushed with a jet of clean dry air or nitrogen. DO NOT
use Freon. For heavier soil, the material can be cleaned by using an ultrasonic bath with double
distilled or deionized water for 2 hours at 40 to 60°C. After this dry the WS-2 piece at 60° C for a
12-hour period (If possible at a vacuum of 1 Torr or less, then purge the vacuum oven with clean dry
air or nitrogen). Caution!! Never use soap-water, alcohol, and organic or any other cleaners for WS2. This will cause a big loss of reflectivity in the UV reflectance.
