Introduction
Product Overview
The Ocean Optics QE Pro Spectrometer is a scientific-grade spectrometer that is ideal for researchers and
industrial customers. Its broadband sensitivity, from UV to NIR, makes it suitable for a wide range of
applications, while its high sensitivity and thermo electric cooler enable effective measurements at very
low light levels. The QE Pro also has the highest dynamic range of any fiber optic CCD spectrometer in
its class.
Two LEDs are provided to monitor spectrometer and TEC operation. The QE Pro operates from power
provided from a separate +5VDC power supply.
Ocean Optics QE Pro High-Sensitivity Fiber Optic Spectrometer
The QE Pro features a Hamamatsu low-etaloning, back-thinned FFT-CCD detector with a 2-D
arrangement of pixels (1044 horizontal x 64 vertical) that is responsive from 200-1100 nm and has a peak
quantum efficiency of ~90% (with a QE of 65% at 250 nm). The detector’s columns are binned, or
summed, inside the detector prior to the readout process, thereby minimizing readout noise. Additionally,
the detector can be cooled from 40°C below ambient up to 50°C with the onboard TE-Cooler to reduce
dark noise. The reduction of noise and dark signal allows integration times of the spectrometer (analogous
to the shutter speed of a camera) of up to 60 minutes, which greatly enhances the detection limit in lowlight level applications. The back-illuminated detector has enhanced response in the UV. The inherent UV
response eliminates the need for UV-sensitive detector coatings that can be difficult to apply consistently
from batch to batch.
The combination of the spectrometer’s low-noise detector and 18-bit A/D Converter delivers a dynamic
typical range of ~85,000:1 and a signal-to-noise ratio of 1000:1 (at full signal).
Replaceable slits are offered for added convenience.

1: Introduction
The QE Pro’s onboard module has 10 user-programmable digital I/O lines for interfacing to other
equipment; and a pulse generator for triggering other devices. You can use the I/Os to flash a lamp,
stop/start a process, and send a message/alarm during the spectrometer’s integration period. The
spectrometer’s operating parameters can be controlled through software. In fact, wavelength calibration
coefficients unique to each spectrometer are programmed into a memory chip right on the spectrometer.
The QE Pro’s high-speed electronics have been designed for considerable flexibility in connecting to
various modules and external interfaces, including PCs, PLCs and other embedded controllers, through
USB 2.0 or RS-232 communications.
A +5 VDC external power supply is required to operate the spectrometer. This power supply is included
with your spectrometer.
An optional internal shutter is available as a configurable version (INTERNAL-SHUTTER-LRGBENCH) to make it easier to take dark measurements and when you need fast integration times with the
best possible signal. This optional feature is especially valuable for probe-based or emissive
measurements where it is more difficult to introduce a shutter into the optical path. The shutter can be
added to an existing QE Pro for an extra charge.
Models
The QE Pro is custom configurable for your specific application. In addition, the following preconfigured
models are offered:



QE Pro-ABS – For absorbance, reflection, irradiance and transmission measurements with a
wavelength range of 200 – 950 nm

1: Introduction
EEPROM Utilization
Nonvolatile memory in each QE Pro contains wavelength calibration coefficients, linearity coefficients,
and a serial number unique to each individual spectrometer. The OOI software application reads these
values directly from the spectrometer, enabling the ability to “hot-swap” spectrometers between
computers without entering the spectrometer coefficients manually on each computer.
About Ocean Optics Software
OceanView is the latest generation of operating software for all Ocean Optics spectrometers. It is a
completely modular, Java-based spectroscopy software platform that operates on Windows, Macintosh
and Linux operating systems. The software can control any Ocean Optics USB spectrometer and device.
OceanView is a user-customizable, advanced acquisition and display program that provides a real-time
interface to a variety of signal-processing functions. With OceanView, you have the ability to perform
spectroscopic measurements (such as absorbance, reflectance, and emission), control all system
parameters, collect and display data in real time, and perform reference monitoring and time acquisition
experiments. Consult the OceanView manual for hardware requirements when using OceanView (see
Product-Related Documentation).
Sampling System Overview
How Sampling Works
Ocean Optics components function in a sampling system as follows in this example:
1. The user stores reference and dark measurements to correct for instrument response variables.
2. The light transmits through an optical fiber to the sample.
3. The light interacts with the sample.
4. Another optical fiber collects and transmits the result of the interaction to the spectrometer.
5. The spectrometer measures the amount of light and transforms the data collected by the
spectrometer into digital information.
6. The spectrometer passes the sample information to Ocean Optics software.
7. Ocean Optics software compares the sample to the reference measurement and displays processed
spectral information.
Modular Sampling Accessories
Ocean Optics offers a complete line of spectroscopic accessories for use with the QE Pro. Most of our
spectroscopic accessories have SMA connectors for application flexibility. Accordingly, changing the
sampling system components is as easy as unscrewing a connector and replacing an accessory.
Interface Options
The QE Pro has both USB and serial port connectors (with the use of an adapter), enabling you to connect
the spectrometer to a desktop or notebook computer via a USB port or serial port.

3: Troubleshooting
3. Locate the unknown device (marked with a large question mark). Right-click on the Unknown
Device listing and select the Uninstall or Remove option.
4. Click the OK button to continue. A warning box appears confirming the removal of the Unknown
Device. Click the OK button to confirm the device removal.
5. Disconnect the QE Pro from your computer.
6. Replug the spectrometer into your computer.
The system should now be able to locate and install the correct drivers for the USB device.
Apple Mac OSX Operating Systems
Since there are no device files for the QE Pro Spectrometer in a Mac operating system, you should not
encounter any problems if you installed the spectrometer before the operating software.
Linux Operating Systems
For Linux operating systems, all you need to do is install the software, then unplug and replug in the
spectrometer. Technically, the driver files for Linux simply give nonprivileged users permission to use
newly connected hardware. There isn’t any long-term harm to plugging in the device before installing the
software.

Appendix A
Calibrating the Wavelength of
the QE Pro
Overview
This appendix describes how to calibrate the wavelength of your spectrometer using SpectraSuite
spectrometer operating software. Though each spectrometer is calibrated before it leaves Ocean Optics,
the wavelength for all spectrometers will drift slightly as a function of time and environmental conditions.
Ocean Optics recommends periodically recalibrating the QE Pro.
About Wavelength Calibration
You are going to be solving the following equation, which shows that the relationship between pixel
number and wavelength is a third-order polynomial:
p = I + C1 p + C2 p2 + C3 p3
Where:
 = the wavelength of pixel p
I = the wavelength of pixel 0
C1 = the first coefficient (nm/pixel)
C2 = the second coefficient (nm/pixel2)
C3 = the third coefficient (nm/pixel3)
You will be calculating the value for I and the three Cs.

A: Calibrating the Wavelength of the QE Pro
Calibrating the Spectrometer
Preparing for Calibration
To recalibrate the wavelength of your spectrometer, you need the following components:

A light source capable of producing spectral lines
Note
Ocean Optics’ HG-1 Mercury-Argon lamp is ideal for recalibration. If you do not have an
HG-1, you need a light source that produces several (at least 4-6) spectral lines in the
wavelength region of your spectrometer.



A QE Pro spectrometer
An optical fiber (for spectrometers without a built-in slit, a 50-m fiber works best)
A spreadsheet program (Excel or Quattro Pro, for example) or a calculator that performs thirdorder linear regressions
Note
If you are using Microsoft Excel, choose Tools | Add-Ins and check AnalysisToolPak
and AnalysisTookPak-VBA.
Calibrating the Wavelength of the Spectrometer
► Procedure
Perform the steps below to calibrate the wavelength of the spectrometer:
1. Place the spectrometer operating software into Quick View mode in OceanView and take a
spectrum of your light source. Adjust the integration time (or the A/D conversion frequency) until
there are several peaks on the screen that are not off-scale.
2. Move the cursor to one of the peaks and position the cursor so that it is at the point of maximum
intensity.
3. Record the pixel number that is displayed in the status bar or legend (located beneath the graph).
Repeat this step for all of the peaks in your spectrum.
4. Use the spreadsheet program or calculator to create a table like the one shown in the following
figure. In the first column, place the exact or true wavelength of the spectral lines that you used.
In the second column of this worksheet, place the observed pixel number. In the third column,
calculate the pixel number squared, and in the fourth column, calculate the pixel number cubed.

7. Record the Intercept, as well as the First, Second, and Third Coefficients. Additionally, look at
the value for R squared. It should be very close to 1. If not, you have most likely assigned one of
your wavelengths incorrectly.
Keep these values at hand.

It also includes accessory connector pinout diagrams and pin-specific information.
How the QE Pro Works
Below is a diagram of how light moves through the optical bench of a QE Pro Spectrometer. The optical
bench has no moving parts that can wear or break; all the components are fixed in place at the time of
manufacture.

QE Pro Components Table
Ocean Optics permanently secures all components in the QE Pro at the time of manufacture. Only Ocean
Optics technicians can replace interchangeable components, where noted.
Item
Name
Description
1
SMA Connector
Secures the input fiber to the spectrometer. Light from the input fiber enters the
optical bench through this connector.
A dark piece of material containing a rectangular aperture, which is mounted
directly behind the SMA Connector. The size of the aperture regulates the
amount of light that enters the optical bench and controls spectral resolution.
2
Interchangeable
Slit
You can also use the QE Pro without a Slit. In this configuration, the diameter
of the fiber connected to the QE Pro determines the size of the entrance
aperture.
The user can change the slit. Ocean Optics also offers a range of FC
connector slits in the same wavelengths, with the product code INTFC-XXX.
An INTFC-KIT is also available.
3
Filter
Restricts optical radiation to pre-determined wavelength regions. Light passes
through the Filter before entering the optical bench. Both bandpass and
longpass filters are available to restrict radiation to certain wavelength regions.
Only Ocean Optics technicians can change the Filter.
4
5
Collimating
Mirror
Grating
Focuses light entering the optical bench towards the Grating of the
spectrometer.
Light enters the spectrometer, passes through the SMA Connector, Slit, and
Filter, and then reflects off the Collimating Mirror onto the Grating.
Diffracts light from the Collimating Mirror and directs the diffracted light onto
the Focusing Mirror. Gratings are available in different groove densities,
allowing you to specify wavelength coverage and resolution in the
spectrometer.
Only Ocean Optics technicians can change the Grating.
6
7
Focusing Mirror
Back-thinned
Area Detector
with TE Cooling
Receives light reflected from the Grating and focuses the light onto the CCD
Detector or L2 Detector Collection Lens (depending on the spectrometer
configuration).
Provides 90% quantum efficiency and bins pixels in a vertical column to
acquire light form the entire height of the spectrometer’s slit image. This
improves light collection and signal-to-noise significantly. This 2D area detector
is back-thinned (back-illuminated) and does not require the detector upgrade
that is normally applied to other detectors.
Only Ocean Optics technicians can add or remove the Detector.

See About Ocean Optics Software.
Alternately, the QE Pro has a serial port for connecting to PCs, PLCs, and other devices with a Windows
32-bit operating system that support the RS-232 communication protocol. However, this connection
method requires an external power supply to power the QE Pro, the HR4000 Breakout Box, and a serial
cable.
