Optical System
The internal optical components of the camera should always be protected.
If no lens or TV adapter incorporating optics is screwed into the camera's
C-Mount thread, the camera's sensor and IR-filter must be protected by
screwing the protective cap onto the camera's C-Mount thread.
Cleaning the Infrared Barrier Filter or Protective Lens
Contamination of the infrared filter or the protective lens has an adverse
effect on the quality of the resulting image (dark points, cloudy structures in
the image). If there is dry dust on the front side of the infrared filter, you can
remove it with a soft brush or with cotton (wool) after unscrewing the lens
or TV adapter.

Installation
Important Note on the Use of C-Mount Objectives
The camera can be mounted onto microscopes with standard TV-adapters
with C-mount connections. Carl Zeiss supplies the camera complete with a
pre-mounted infrared barrier filter, which offers the optical advantage for
use on microscopes of a lower sensitivity to dust.
The IR barrier filter is situated approx. 11 mm behind the outer edge of the
C-mount opening in the camera.
Due to this pre-mounted IR barrier filter, C-mount objectives that
screw more than 11 mm into the thread cannot be screwed into
the camera.

2.1
General
The Axiocam 105 color is a high-resolution digital camera for color images.
It has been designed to be used in the field of light microscopy for general
observation, routine work, and simple applications in which a sufficient
amount of light is available.
The camera is particularly well suited for materials microscopy applications
or for the acquisition of images of stained or naturally colored microscopic
specimens. Because of its small size, the camera is also well suited for

Adjust Property Page
This property page contains a summary of the most important camera
settings, which are constantly used during operation.
The property page is split into the fields Exposure, White Balance (with
color settings) and Histogram (for the display of an image histogram).
Axiocam 105 color Installation + Reference Guide
21
Image Acquisition
Exposure
The camera’s exposure time can be adjusted to the lighting conditions on
the microscope using a slider or by entering an exposure time directly into
the input field. When entering the exposure time manually you can state the
value range directly using the abbreviations "ms" for milliseconds and "s"
for seconds.
Exposure time measurement
The program assists in calculating an optimum exposure time, at which the
camera will be maximally saturated without being overexposed. To perform
this calculation, click on the
button.
The exposure time calculated is available for subsequent images. It can be
changed at any time by moving the slider or by entering a new exposure
time manually.
This measurement function uses all the image information from the camera
sensor for the exposure measurement as standard (integral measurement).
Weighting of exposure time measurement
During an exposure time measurement an attempt is made to expose the
camera in such a way that the sensor is not overexposed in any area of the
image. The value calculated therefore corresponds to 100% of the
camera’s maximum exposure range.
The exposure time measurement can also be adjusted to particular lighting
conditions. If under certain acquisition conditions the exposure time
measurement does not achieve satisfactory exposure of the areas of the
image in which you are interested, it is possible to influence the result of
this measurement by adjusting the weighting.
A setting of 50% means that by pressing the
button, 50%
of the exposure time is measured and set for actual acquisition.
The setting range is between 10% to 200%.
22
Printed 10.2013
Image Acquisition
Automatic Exposure
The Auto Snap feature is not available for the Axiocam 105 color.
If the Auto Live check box is activated, the software continuously sets the
exposure during the live image. In this way it is possible to generate
images with the correct exposure without having to manually enter an
exposure time. The exposure time currently calculated in the live image is
used for each individual image.
The exposure measurement button
can be pressed at any
time. The Auto Live function will then be deactivated. This is useful if you
want to update the exposure time for a current live image.
Note:
 In this mode it is not possible to edit the exposure times in the
multichannel mode for the individual channels.
White Balance
In order to achieve a color display which is neutral and close to reality it is
necessary to balance the individual color channels against one another.
This requires a scene without a sample to be set in the microscope. The
scene should be white, neutral and illuminated as evenly as possible. It
must not be overexposed.

: Using this button you can specify a reference point for
the white balance yourself. To do this, use the pointer to click on a
white area in the live image.

: Starts the measurement. The weighting factors
calculated for the color channels are then displayed.

: Using this button you can switch back to the basic white
balance setting. This setting is optimized for a halogen light
temperature of 3200 K.
Axiocam 105 color Installation + Reference Guide
23
Image Acquisition

: Using this button you can switch back to the basic LED white
balance setting. This setting is optimized for a LED light temperature of
5500 K.
Color Adjustment
Using the color sliders you can increase or decrease the proportion of each
basic color. Please note that each time a change is made, a proportionate
adjustment of the other colors also takes place automatically. The use of
the color sliders is recommended in particular for manual adjustment of the
white balance in image regions that are completely filled. Here the
automatic method can lead to color distortion. In this case also try the 3200
K standard setting as an alternative.
Notes:
 Please note, that the display curve has to be adapted to the gamma
value 0.45 in the histogram for a realistic color reproduction.
On a microscope, however, the brightness of a halogen lamp is often
adjusted by changing the lamp voltage. This changes the color of the light
emitted at the same time, though.
By moving the
slider it is possible to adjust the
target color value of the white balance to the color temperature of the
halogen illumination.
At the middle setting, the color white (R=B=G) is taken as a neutral value.
This neutral value can also be achieved at any time by clicking on the
Reset button.
Alternatively, you can influence the color channels individually by activating
Show channels:
Clicking on the buttons

These changes can be observed immediately in the live image and in the
histogram display.
Note:
 Further information on setting optimum color reproduction in AxioVision
can be found in Chapter 2.6 "Practical Notes on Operation in
AxioVision" - "Notes on optimum color reproduction in AxioVision".
A setting using this method can be saved as a setting with a name of your
choice and subsequently reloaded. Activate the corresponding parameters
(ex: White Balance Red, White Balance Green, White Balance Blue) in the
menu Tools  Settings Editor.
Histogram
A histogram indicates the intensity distribution of the image signal in the
live image and the acquired image. It provides a clear representation of the
brightness distribution in the current image. The horizontal axis
corresponds to the scale of possible intensity values from dark to light and
the vertical axis shows the number of pixels calculated from the current
image which possess this intensity value on the x axis.
With the color camera the value distribution is displayed separately for
each color channel in three lines (red, green and blue).
If an image is overexposed, at least one curve on the histogram is cut off at
the right-hand edge of the display area, where it forms a maximum. Reduce
the exposure time or insert gray density filters into the microscope’s beam
path to reduce the amount of light. It is also possible to reduce the lamp
voltage of the microscope illumination. However, this changes the basic
color of the illumination (color temperature) and requires a new white
balance.
If an image is underexposed, the histogram does not reach the right-hand
edge of the display area. As a result, optimum use is not made of the
camera’s resolvable gray value range. You should therefore increase the
exposure time or the amount of light in the microscope.

Log: By clicking on this button it is possible to influence the histogram
display. You can toggle between a linear scaling and a logarithmic display
of the signals represented in the histogram.
The logarithmic display makes it possible to view small amplitudes and high
peaks at the same time in a single overview. Otherwise, because of the
automatic scaling of the display, small signal values are often not visible in
the diagram.
Skip: This function can be used to influence the automatic scaling of the
histogram. If an image contains an extremely bright glare or extremely dark
features the result will be overexposure or underexposure of the image in
these areas. All of these pixels possess the maximum / minimum numerical
value which can be displayed (e.g. in an 8-bit image 255 for overexposure
or 0 for underexposure). Consequently, for the gray value 255 the
histogram has to display an extremely high number of pixels with the same
value. As the scaling of the histogram curves is automatically adjusted to
this high value, smaller values can no longer be resolved in the display.
By using the Skip function the maximum values at the upper and lower end
of the histogram are omitted during the scaling of the display.

The camera will always acquire a color image, and this is then
converted to a black/white image.

In the drop-down list box underneath you can select from various
camera operation modes.

With the Axiocam 105 color, three modes are available: in the Color
1x1 mode, the resolution from the camera is set to its highest. In
the Color 2x2 and Color 4x4 modes, pixels are combined (in arrays
of 2x2 and 4x4 respectively) to represent 1 pixel. While decreasing
resolution, these modes increase the camera’s light sensitivity,
which is useful for darker samples.
Frame
In this field you can specify whether the frame or the entire area of the
sensor is used for the acquisition.

Refresh overview: This button makes it possible to insert an overview
image into the area where the frame can be positioned. This makes it
extremely easy to target your specific area of interest.
In the displayed overview image a frame can be positioned by using
the mouse, which corresponds to the selected frame of the acquired
image. The shape and size of the frame can be changed by clicking on
and dragging the edges of the frame while holding down the left-hand
mouse button. It is also possible to move the frame by clicking inside it
and keeping the button pressed as you change its position.

Center: By clicking on Center you can automatically center the
selected frame. This can be useful as interesting parts of the sample
are usually moved to the center of the view area. In addition the center
of the view area is the place of the highest optical quality.

Framestart / Framesize: The start point and the selected frame size
will be displayed in these input fields. Alternatively you can enter the

Note:
 Please note that a gamma setting of 0.45 is required for correct color
reproduction. This can be achieved in the Live image by activating the
button. Only the display is influenced by this function. The data
remain unchanged.
Image Orientation
An Axiocam 105 color image is adjusted in such a way that the image
orientation corresponds to the image in the eyepiece when mounted on an
upright microscope with the front of the camera facing you.
Setting options:
 Original
 Vertically reflected
 Horizontally reflected
 Rotated 180 degrees
This starting position can be adapted via this menu to suit your
requirements. If, for example, the camera’s cable routing needs to be
changed on an inverse microscope, the camera can be mounted at a
different angle, without the correspondence between the image orientation
and the eyepiece being lost.
Note:
 Activating an image rotation can reduce the maximum live-image
speed.
Shading Correction
Activate this function if you notice, e.g. with brightfield images, a reduction
in image brightness at the image edge or uneven color representation. For
this calibration process make sure that the camera is viewing a completely
empty image. To ensure that this is the case, move your sample on the
microscope completely out of the field of view.
Axiocam 105 color Installation + Reference Guide
31
Image Acquisition
Shading correction to improve image quality
In microscopy, numerous side effects can have an undesirable influence on
image quality. Dust and particles in the beam path, for example, can leave
dark spots in the image, and, under certain conditions, diaphragms and
optics can cause slight shadowing that increases towards the image edge,
due to unavoidable physical effects.
For all Axiocam models it is possible to acquire a shading reference image
and apply this automatically each time an image is acquired. On the
camera property page General you will find the Shading Correction
button. This can be used to trigger the acquisition and saving of a shading
reference image.
If you are using a motorized microscope or a microscope with an encoded
nosepiece, it is possible to acquire a separate reference image for each
objective. These images are then applied automatically for the objective
that has been selected.
Procedure for generating objective-specific shading correction
Prerequisites:


Encoded or motorized microscope stand.
Camera belonging to the Axiocam family.
The following steps are required to set and apply shading correction in the
optimum manner:

Activate the Automatic check box on the camera property page
General.

Make sure that all motorized and encoded microscope components are
correctly configured in the Micro Toolbox. For the automatic application
of shading correction, the correct configuration of the available
objectives and the cameras is particularly important (please also refer
to the MTB2004 Configuration manual).

Set the light intensity with which you want to work.
32
Printed 10.2013
Image Acquisition

To do this, set a suitable exposure time and the white balance of the
camera.

Set Köhler illumination on the microscope (if using transmitted light) in
order to create a reproducible image-acquisition situation.

Create a test image of a specimen with quality that is as high as
possible.

Check the quality of the Köhler setting for each objective with which
you want to generate automatic shading correction.

Now move the sample out of the camera’s field of view and bring the
microscope clearly out of focus.

Generate a shading reference image for each objective, one after the
other, by clicking on the Shading Correction button on the camera
property page General.

If you are using a fully motorized microscope, it is very easy to save
and reload the configuration of the light path setting in a hardware
setting:
 Light intensity
 Gray density filter
 Setting of the condenser aperture diaphragm and field diaphragm

You can now refocus the microscope and work with the automatic
shading correction.
Notes:
 The reference images generated are saved on a user-specific basis. All
users who have their own login must therefore generate their own set
of reference images.

Automatic shading correction only takes into account the changing of
the objective. Changes to the settings of other optical components,
such as an Optovar, the camera adapter or the condenser, are not
taken into account and will make it necessary to repeat the generation
of the reference images.
Axiocam 105 color Installation + Reference Guide
33
Image Acquisition

If several cameras are operated on a system (e.g. an AxioCam MRm
and an AxioCam IC), the reference images for each camera will be
managed separately.

In the Multidimensional Acquisition function, a function for
fluorescence-channel-specific shading correction is offered under
Extended parameters on the C (Channel) property page.

Activating shading correction can reduce the maximum possible speed
of the live image.
Applying object-specific shading correction
Activate the Automatic check box on the camera property page General.
Note:
 Make sure that the shading reference images generated are still having
the desired effect if the images were generated some time ago. They
will need to be generated again in any case if the optical settings of the
microscope have been changed. This applies to the following settings
in particular:
 Lamp adjustment
 Köhler setting
 Optovar
 Camera adapter
 Camera port
Applying shading correction manually
With non-motorized and non-encoded microscopes the automatic shading
correction cannot be activated. But it is possible to carry out shading
correction using a previously generated standard reference image. This
image is applied irrespective of the objective set.
34
Printed 10.2013
Image Acquisition
To generate this file, follow the procedure described above. However, this
function can only be carried out for one objective. As a compromise for all
available objectives, you can perform this using an objective with a medium
magnification. For special requirements you will need to carry out shading
correction again, specifically for the objective you are using, prior to the
acquisition of an image.
Shading correction via image processing
For advanced users it is also possible to carry out shading correction via an
image processing function. On the Processing menu  Adjust 
Shading Correction you will find a function that allows you to perform
targeted subsequent processing. This function can be used in a script to
allow you, for example, to generate and apply an image with an assigned
shading correction for each objective.

Notes on Optimum Color Reproduction in AxioVision
Below you will find a detailed description of how best to set up AxioVision
to achieve optimum color reproduction with the Axiocam 105 color.
Note:
 For an optimum color reproduction the monitor first has to be adjusted.
To do so please use a well-suited image.
Adjusting the display characteristic curve in AxioVision
In order to achieve optimum reproduction of color images of the Axiocam
105 color on a monitor, the display characteristic curve must be used to set
"gamma compensation". The advantage here is that only the display is
influenced and the actual data will remain unchanged. Further details on
this can be found below. The settings can be done as follows:

With the mouse click on the icon
in the footer of the live image.
This adjusts the display characteristic curve automatically for an
optimum color reproduction of the monitor (gamma = 0.45).

Or in an already acquired image: In the Properties dialog window, set
the gamma characteristic curve in the histogram image on the Display
property page.
Note:
 This also influences the reproduction of the color saturation.

Clicking on this icon
returns to a linear display of the data.

Information for Displaying Axiocam Images in
AxioVision
So that intelligent use can be made of this feature, in AxioVision it is
possible to influence the display using the characteristic curve.
To do this, right-click in the image acquired and select from the context
menu the Properties function. The dialog window Properties is displayed
on the screen:
38
Printed 10.2013
Image Acquisition
You can now select the area to be displayed by dragging the black
rectangles along the characteristic curve or carry out automatic
optimization by clicking on the corresponding buttons.
A histogram of the gray and color values will be displayed which makes the
gray and color distribution visible.
The Best Fit, Min/Max and Linear buttons can be used to quickly adjust
the histogram display. You can influence the display by clicking on the Log
or Skip buttons.
Best Fit calculates in the current histogram the values which exclude 1‰
of the pixels contained in the image. The gray/color range calculated in this
way is displayed on the screen. (You can adjust the value of 1‰ to suit
your requirements).
Min/Max displays on the screen the smallest and largest gray or color
value present in the image.
Linear displays on the screen the total possible value range.
Log displays the histogram in a logarithmic scaling, allowing you to
effectively evaluate histograms of images with high dynamics.
Skip: By using the Skip function the maximum values at the upper and
lower end of the histogram are omitted during the scaling of the display.
The
,
and
sliders can be used to change the brightness,
contrast and gamma of the display. This can also be achieved by dragging
the individual "handles" of the characteristic curve in the histogram. You
can adjust the brightness and contrast by changing the left or right-hand
end points of the characteristic curve individually or by shifting the entire
line using the center "handle". The gamma value can be changed by
shifting both "handles".
Click the Save button to store the current settings. You can use these
settings when displaying another image by clicking the Restore button.
This enables you to compare different images.
Axiocam 105 color Installation + Reference Guide

Image Acquisition
If you activate the Apply to all T check box the settings in all the acquired
instants of exposure are applied to the relevant channel.
Note:
 You can get the best display of colored objects, if the gamma setting is
in the range of approx. 0.45.
Recommended Camera Settings
The standard setting installed for 3200 K (3200 K button on the Adjust
property page) often offers the camera the most natural reproduction of the
image situation on the microscope. Here the image background is
reproduced as it appears on the microscope. This setting is also useful in
acquisition situations where no neutral-tint area is available to carry out a
balance manually.
If the image background in the acquired image is to be displayed with a
neutral tint (gray or white), a manual white balance is required. Click on the
Automatic button in the White Balance field.
If the lamp voltage selected on the microscope is too low, the color of the
image background may have been shifted a long way into the red. If a
white balance is carried out in this event, the result may be visible
deviations in the display of the color of the current sample. Correct this
situation by increasing the lamp voltage to achieve a more neutral
background, and insert gray filters into the microscope’s illumination beam
path to adjust the intensity.
The values calculated using the automatic white balance function can be
optimized further with the help of manual settings.
40
Printed 10.2013
Image Acquisition
Now save this white balance setting together with the current lamp voltage
and filter position on the microscope (if available as an adjustable variable)
as an AxioVision hardware setting. This will enable you to achieve
reproducible settings for color reproduction. Details on working with
hardware settings can be found under this keyword in the AxioVision online
help.
Recommended Monitor Settings
The output medium has a significant influence on color perception! Use a
familiar specimen to adjust the brightness and contrast rendering. If
possible also set the color temperature of the monitor to approx. 5000 K or
6500 K.
2.8
Background Information
Gamma Setting
This setting is required to compensate for the inherently non-linear
behavior of the image tube ("gamma"). It also influences the quality of the
color display.
You can get the best display of colored objects, if the gamma setting is in
the range of approx. 0.45.
Many video cameras have built-in gamma compensation, as they are
intended for use on video monitors.
Configurable Toolbars for Operating the Camera
AxioVision allows you to configure your own toolbars. This means that the
procedure can be tailored to your own requirements, and thus optimized.
The size of the toolbar buttons can also be adjusted, helping you to work
quickly with the mouse. A detailed description of how to create toolbars can
be found in Chapt. 9 "Configuration" - "Adapting Toolbars" in the AxioVision
Manual.
