2.3.2 Optical
The camera’s
72 mm x 72 mm cross-section comes with an adapter for F-mount lenses,
which have a 46.50 mm back focal distance.
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 noise, thus decreasing the
SNR.
The cameras are very sensitive in the infrared (IR) spectral region. Color cameras have an
IR cut-off filter installed; monochrome cameras come without an IR cut-off filter. The
camera includes space under the front lens bezel for inserting an IR filter (1 mm thickness
or less) if necessary.
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.
2.3.3 Environmental
The camera operating temperatures range from -40°C to +85°C in a dry environment. The
relative humidity should not exceed 80% non-condensing. Always keep the camera as cool
as possible. Always allow sufficient time for temperature equalization if the camera is
stored below 0°C.
The camera should be stored in a dry environment with the temperature ranging from -
50°C to + 90°C.
