2 Safety Instructions
1. The greateyes CCD cameras are designed to measure weak light or radiation
signals in spectroscopy or imaging applications. greateyes is not liable if you use the
cameras for other purposes.
2. It is not allowed to open the camera housing or the power supply unit. The
warranty claim is lost by opening it.
3. Please only use the provided power and connection cables. Contact greateyes to
get a replacement for a defect cable.
4. Switch off the camera after usage of the system. The camera has no separated
on/off switch, please use the switch on the external power supply unit.
5. Do not use the camera in rooms with high humidity or strong electric or magnetic
fields.
6. greateyes is not liable for personal injuries or material damage which are caused
by neglect of these safety instructions.
3 System Requirements
The greateyes CCD cameras can be used with the following operating systems:
Windows XP 32bit / 64bit
Windows Vista 32bit / 64bit
Windows 7 32bit / 64bit
Windows 8 32bit
In addition you need an USB2.0 port to connect the camera.
4 Properties of the camera
The greateyes cameras are highly sensitive Full-Frame CCD cameras. The whole
area of the CCD sensor is light-sensitive, there are no separate readout registers
along the columns. For this reason the user has to make sure that only during the
exposure time the light reaches the sensor, during the follоwing readout process no
other photons should reach the sensor. For this purpose you can connect a shutter to
the camera or switch the light source on and off with the help of the Sync Output
signal.

Furthermore in several applications it is recommended to take a background image
with the same exposure time before the measurement and then to subtract it from the
measurement. The residual light and the dark signal are thereby drawn off from the
result picture. This increases the image quality.
The greateyes cameras have a peltier cooling for the camera sensor, which can be
adjusted in several levels. The lower the temperature the higher is the power
consumption of the camera. A lower temperature on the sensor reduces the random
noise, but it also slightly changes the spectral sensitivity of the sensor.
5 Startup
5.1 Connection of the camera and driver installation
1. USB2.0 connection: Connect the camera with the USB cable to PC. Remember
that an USB2.0 port is needed.
2. Input Trigger: You can connect an external trigger signal to start the
measurement process of the camera. The measurement starts with a rising edge of a
5V TTL signal, if the camera was set to trigger mode by software.
3. Output Shutter: You can connect an external shutter to the middle socket. In
contrast to the Sync Output, you can set by software delay times for opening and
closing the shutter. Furthermore you can open and close the shutter manually. The
Sync Output may be charged to at most 20 mA.
4. Output Sync: You can connect external equipment to the Sync Output. The Sync
Output provides a 5V TTL signal while exposure time of the camera. The Sync
Output may be charged to at most 20 mA.
5. Power supply: Connect the camera to the power supply unit with the 12PIN
power cable. Connect the power supply unit with the IEC power cable to a power
socket and turn it on.

6 Software Operation
6.1 Preliminary note
The input fields of the software change their colour from blue to yellow when
changing the parameters. The new parameters are accepted only by pressing the
Enter key. If the colour does not change back to blue after pressing the enter key, the
entered value is outside of the value margin.

6.2 Camera options
Please go to register sheet CameraOptions now:
The buttons and fields in the red marked areas are explained below:
Temperature Controller: The greateyes camera contains a peltier cooling for the
sensor. With activated cooling, the noise level of the sensor decreases, which
increases the quality of the picture.
You can deactivate the cooling with No Control or choose several temperatures in
the selection menu. Right next to it you see the actual temperature on the sensor and
on the camera head, where the heat is dissipated. If the head gets 55 °C or higher
the cooling is deactivated automatically. In this case you get a hint from the software
and should connect a water cooling to the camera.
Hint: The temperature of the sensor is also shown in the info line of the software. If
you change the temperature or restart the software, you have to wait some minutes
until the temperature is reached, before you start a new measurement.
Correct bad pixel: The sensor can have several pixel failures because of its
sensitivity, which can be corrected by software. These pixels are brighter than the
surrounding pixels. Select Correct bad pixel to correct them. The adjoining digit
effects the value behind the decimal point of the correction factor.

copyright © greateyes GmbH 8
E.g.: All pixels are corrected which are 1.2 times brighter than the surrounding pixels,
if you enter the value 2.
Bias Correction: The camera sensor has in each row left and right of the scene
some dark pixels that are not shown in the picture. These pixels can be used to
compensate for slight differences in the dark noise between the lines, if Bias
Correction is activated.
Gain Setting: To adjust the pre-amplification you can choose between two modes. In
Mode Max. Dynamic Range the sensor signal is not amplified before digital
conversion. In Mode Highest Sensitivity the signal is amplified, which is useful for
weak signals, but the noise is also amplified.
Auto Shutter: Check this box to activate the auto shutter mode. The shutter opens
and closes with every measurement according the entered times:
Open time: Enter the time which is needed at least to open the shutter.
Close time: Enter the time which is needed at least to close the shutter.
Open/Close Shutter: Opens or closes the shutter manually.
Pixel frequency: Choose the pixel readout frequency for the camera. With a higher
frequency the data are transferred faster from the camera to PC, but thereby quality
losses are possible.
Crop Mode: By activating the crop mode it appears an additional field where you can
enter a number of lines. In this mode only a part of the sensor is read out and the
read out time is reduced.
Vertical Binning: Choose a binning mode for vertical binning. In vertical binning the
signal values of successive rows are added up to one row directly in the sensor. The
overall picture has fewer rows with more signal intensity. The binning mode sets the
number of rows, which are added.

copyright © greateyes GmbH 9
Sub Image: As a special function in the vertical binning, you can activate the sub
image. You can now specify an area between two lines, which is read out binned to
one line.
Horizontal Binning: Choose a binning mode for horizontal binning. In horizontal
binning the signal values of successive columns are added up to one column by
software. The overall picture has fewer columns with more signal intensity. The
binning mode sets the number of columns, which are added together.
Autocheck: Activate this function to connect the camera automatically to software.
Connect: Connects the camera manually.
CloseCam: Disconnects the camera
6.3 Camera control
Please go to register sheet Operation now:
The buttons and fields in the red marked areas are explained below:
Cam L: This field is green, if the connection to the camera is established and the
camera is turned on. If you have connected another camera it appears a second field
and you can choose between one and both cameras. If you have choosen both
cameras the pictures are combined by the software.

copyright © greateyes GmbH 10
Integration Time: Enter here an integration time between 1 ms and 2.000 s for a
measurement. You can choose between unit ms and sright next to it.
incl. Background: Enable this feature to automatically add a background image
before every single shot that can be subtracted from the single shot. There will be
two measurements in a row, wherein the trigger output SYNC is switched only during
the second measurement during the exposure.
each Frame: In video mode, you can also decide whether you only want to perform a
background measurement at the beginning or at each new image.
Single Shot: Starts a Single Shot with specified Integration Time.
The image is stored as a measurement. If incl. Background is checked, a
background image is automatically taken and saved as background.
Video Mode: Starts a continuous sequence of single shots. The last measurement is
always overwritten by the current. If incl. Background is checked, a background
image is automatically taken once and saved as background. If each Frame is
checked, a background image is automatically taken with every single shot and
saved as background.
Burst: In burst mode the camera automatically performs several measurements. In
contrast to the video mode all measured data are transmitted in a complete package
and are shown as one image in the software.
Hint: In burst mode it could be that a large amount of data has to be transferred
depending on the number of measurements and the selected binning mode. You
should close all unnecessary background programs to ensure that the data can be
transferred correctly.
Number of Frames: Enter here the number of measurement for the Burst Mode.
Take background: Starts a manual background measurement, which is stored as
Background.
Hint: A new background measurement (manual or automatic) overwrites the last
background.
Shutter locked while taking background: Keeps the shutter closed, while taking a
background measurement.
Delete Background: Removes the current background from memory.
ext. Trigger: Sets the camera in trigger mode by pressing Single Shot, Video
Mode, Burst Mode or Take background. In trigger mode the camera waits for a
trigger signal on the trigger input. The measurement starts whenever a 5V TTL signal
on high level is applied to the trigger input. The camera waits for 65s, after that it
returns to normal mode. In Video Mode and Burst Mode a trigger signal for each
measurement is needed.
