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.
Environmental
The camera operating temperatures range from -40 °C to +70 °C in a dry environment. The
relative humidity should not exceed 90% 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.
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 or in close
proximity to an intensive heat source, strong magnetic fields, or electric fields.
3.
Avoid touching or cleaning the front surface of the optical sensor. To clean the
sensor, use only a soft lint-free cloth and an optical cleaning fluid.
Do not use methylated alcohol!
