1. Video Camera VC45 1.2 CCD Sensor Overview The following CCD sensors can be used in the camera: CCIR format resolution pixel size active sensor 1/2“ 741 x 576 pixel 8.6 x 8.3 µm 6.4 x 4.8 mm 2/3“ 741 x 576 pixel 11.6 x 11.2 µm 8.6 x 6.5 mm... -
Page 8: Spectral Response
= with infrared cutting filter 1.3 Connections Lens Mount The VC45 uses a C-Mount with a standard back focal length of 17.52mm (distance between the front edge of the C-Mount in- sert and the focal plane of the CCD sensor). The C-Mount has a fine adjustment to allow for small variations in the focal length of instruments. -

1. Video Camera VC45 Long Exposure in Frame Mode By using the EXP (= exposure) input (pin 3 of the 12-pin socket) the integration time can be controlled. In line 10 of the video signal a marker pulse is allocated. If in this moment the EXP signal is "high", the marker pulse is sup-... -
Page 16: Shutter Mode
1. Video Camera VC45 Shutter Mode In the shutter mode, exposure times between 1/50 ... 1/10000 s can be realized. These shutter times can be achieved by a par- allel and serial programming via external signals (ENB, ED0, ED1, ED2) or by a parallel setting via internal DIP switches. -
