MECHANICAL, OPTICAL, and ENVIRONMENTAL
1.6.1 Mechanical
The camera housing is manufactured using high quality zinc-aluminum alloy and
anodized aluminum. For maximum flexibility the camera has eight (8) M3X0.5mm
mounting screws, located towards the front and the back. An additional plate with ¼-
20 UNC (tripod mount) and hardware is shipped with each camera. Mechanical
drawings for C4080 and C2880 Camera Link output cameras are found in Figures
1.7a to 1.7b below. All dimensions are in millimeters.
1.6.2 Optical
The C4080 camera (72 x 72) mm cross-section comes with an adapter for F-mount
lenses, which have a 46.50 mm back focal distance and the C2880 camera (also 72 x
72) mm cross-section comes with an adapter for C-Mount lenses which have a 17.5
mm.
The camera performance and signal to noise ratio depends on the illumination
(amount of light) reaching the sensor and the exposure time. Always try to balance
these two factors. Unnecessarily long exposure will increase the amount of noise and
thus decrease the signal to noise ratio.
The cameras are very sensitive in the IR spectral region. All color cameras have and
IR cut-off filter installed. The monochrome cameras are without IR filter. If
necessary, an IR filter (1 mm thickness or less) can be inserted under the front lens
bezel.
CAUTION NOTE
1.
Avoid direct exposure to a high intensity light source (such as a laser beam).
This may damage the camera optical sensor!
2.
Avoid foreign particles on the surface of the imager.
1.6.3 Environmental
The camera is designed to operate from -40
0
to 85
0
C in a dry environment. The
relative humidity should not exceed 80% non-condensing. Always keep the camera
