The smaller body BOBCAT HD-SDI cameras (46 x 46) mm cross-section
come with an adapter for C-mount lenses, which have a 17.52 mm back focal
distance – illustrated in Figure 1.15 and Figure 1.16. An F-mount lens can be
used with a C-mount camera via an F-mount to C-mount adapter, which can be
purchased separately – refer to the Imperx web site for more information. 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.
