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.. All dimensions
are in millimeters.
1.6.2 Optical
The camera (72 x 72) mm cross-section comes with an adapter for F-mount lenses,
which have a 46.50 mm back focal distance.
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 an
IR cut-off filter installed. The monochrome cameras come without IR cut filter. If
