The Cheetah cameras come with varying adapters for C-mount or F-mount lenses that have
different back focal distances (see
). You can use an F-mount lens with a
C-mount camera using an F-mount–to-C-mount adapter (with POE-C2010, POE-C2410,
POE-C3210, POE-C4010, and POE-C4110 cameras only). You can purchase the adapter
separately (refer to the Imperx web site for more information).

Camera performance and signal to noise ratio (SNR) depend on the illumination (amount of
light) reaching the sensor and the exposure time. Always try to balance these two factors.
Unnecessarily long exposures increase the amount of dark noise and thus decrease the signal
to noise ratio.
The camera is highly sensitive in the infrared (IR) spectral region. All color cameras have an IR
cut-off filter installed. Monochrome cameras do not have any optical filter. If necessary, the
monochrome camera can accommodate an IR filter (1 mm thickness or less) inserted under
the front lens bezel.
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.
