The Cheetah 3G-SDI camera cross-section comes with an adapter for C-mount
lenses that have a 17.52 mm back focal distance. You can use an F-mount lens
with a C-mount camera using an F-mount
–
to-C-mount adapter. You can purchase
the adapter separately (refer to the Imperx web site for more information).
Camera performance and signal to noise ratio 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
noise and thus decrease the signal to noise ratio.
The camera is highly sensitive in the IR spectral region. All color cameras have an
IR cut-off filter installed. Monochrome cameras do not have an IR filter. If
necessary, the 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.
2.5 Environmental
Operate the camera in a dry environment with temperatures between -40°C and
+85°C. Relative humidity should not exceed 80% non-condensing.
Always keep the camera within temperature specifications.
The camera should be stored in a dry environment with the temperature ranging
from -40°C to + 90°C.
1.
Avoid direct exposure to moisture and liquids. The camera housing is
not hermetically sealed and any exposure to liquids may damage the
camera electronics!
2.
Avoid operating in an environment without any air circulation, in close
proximity to an intensive heat source, strong magnetic or electric fields.
3.
Avoid touching or cleaning the front surface of the optical sensor. If the
sensor needs cleaning, use soft lint free cloth and an optical cleaning
fluid.
Do not use methylated alcohol!

cleaning procedures.
