The Cheetah camera provides an adapter for C-mount lenses that have a 17.53 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!
Contact Imperx support for cleaning procedures.
