Effective camera dynamics: ≥1:1000 (≥60 dB)
Digital RS-644 output with 12-bit (LVDS)
One output (40 Mpixel/s)
Very compact design
With a resolution of 2048 x 2048 effective pixels, the CCD-4000UV is a further member of the high
resolution VDS Vosskühler CCD camera family.
Due to a special CCD as well as the use of quartz glass as input window, the camera offers a good
sensitivity up to the 190…200 nm UV-area.
The CCD-4000UV supplies 7.5 frames/sec. at a full resolution. Even 15 frames/sec. can be achieved
in the binning mode 2048 (H) x 1024 (V).
By means of the progressive interline transfer sensor very short exposure times up to 1/10000 sec. can
be achieved at a full resolution. The exposure time can be regulated in steps of approx. 64 µs. Due to
the asynchronous operation (image on demand) the exposure starts 15 µs after an external trigger
pulse. Therefore the camera is especially useful for recording moving objects.
The effective dynamics of the complete camera

is more than 1000 and therefore offers reserves even for difficult lighting conditions or very short
exposure times.
The RS-644 digital output supplies image data with 12-bit precision.
On the basis of the C-mount connection different C-Mount lenses and adapters for F-Mount can be
used.
The CCD-4000UV is identical regarding the mechanic and pin-compatible to the CCD-1300 camera
line.

4.2 Power Supply
The camera requires 12 V +5 %, at a current capacity of maximum 620 mA. If the camera does not
output an image in the image-on-demand mode, the current capacity decreases to approx. 500 mA.

4.3 Mode Input (Image on Demand)
The mode input serves for the switch between the continuous operation with 133 ms exposure time
and the shutter- and image-on-demand operation and is shown by the LED IOD on the backside of the
camera.

The shutter time texp can be regulated between 100 µs and 5 ms via trimmer ST at the back of the
camera. For the control an oscilloscope should be connected at the exposure output (wiring with a
resistor on the supply voltage).
If the trigger input is active longer than the adjusted shutter time texp, the shutter time texp automatically
extends to the active time at the trigger input. With this, also exposure times to the second area are
achievable.
As further trigger- and exposure control input the /TREX input is available at the 37-pin digital output
(see page 11).

The exposure output indicates the active exposure time of the sensor in the image on demand
operation. At the end of the exposure this output stays active 64 µs (1 line) longer than the real
exposure. The active exposure is also indicated by the LED Exp. on the backside of the camera.
After the image record the 2048 active lines of the image are given out at the digital output. This
image output is shown by LED Fout on the backside of the camera.

5.6 Trigger Input TREX
Via trigger input /TREX the shutter time of the camera at the image on demand operation can also be
fixed. The input can be used either as RS-422A input (TREX and /TREX) or only as /TREX active-low
input. For the RS-422A operation a termination resistance of 100 ohms can be connected internally in the
camera.
Activating the TREX input, the active exposure of the sensor starts with 15 µs delay and stays active as
long as the TREX input is active. So the exposure time can be indicated spaciously by the user.

5.7 Increasing of the Video Gain
The analog video gain of the camera can be increased by factor 2 (+ 6 dB) via input /SV 2 (active low).
This is advantageous especially at very short shutter times or bad lighting conditions. The input is TTL –
compatible (high > 2V, low < 0.8 V).
5.8 Switching to 15 Images/Sec. (Binning)
With the trigger input /BIN (active low) it is possible to switch up to 15 images/sec. at 2048 (H) x 1024
(V) pixels. At an opened input it is possible to give out 7.5 images/sec. at full resolution. The input is
TTL – compatible (high > 2V, low < 0.8 V).
