The Cheetah 10GigE SFP cameras come with an adapter for F-mount lenses that have a 46.50
mm back focal distance.
The camera can also be equipped with M42, Canon EF EOS Active or Passive mounts (refer to the
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.
Avoid direct exposure to a high intensity light source
(such as a laser beam). This may damage the image
sensor!
Avoid foreign particles on the surface of the image
sensor
.
Do not use methylated alcohol for cleaning the image
sensor!
Please refer to the Sensor Cleaning Procedure document
found in the camera’s information ZIP file or contact
Imperx support for cleaning procedures.
Avoid touching or cleaning the front surface of the
image sensor. If the sensor needs cleaning, use soft lint
free cloth and an optical cleaning fluid.
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.
