2.3.2 Optical
The C4080 camera (72 x 72) mm cross-section comes with an adapter for F-mount lenses,
which have a 46.50 mm back focal distance and the C2880 camera (also 72 x 72) mm
cross-section comes with an adapter for C-Mount lenses which have a 17.5 mm.
The camera performance and signal to noise ratio depends on the illumination (amount of
light) reaching the sensor and the exposure time. Always try to balance these two factors.
Unnecessarily long exposure will increase the amount of noise and thus decrease the
signal to noise ratio.
The cameras are very sensitive in the IR spectral region. All color cameras have and IR cut-
off filter installed. The monochrome cameras are without IR filter. If necessary, an IR filter
(1 mm thickness or less) can be 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.
2.3.3 Environmental
The camera is designed to operate from -400 to 850 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 was
kept below 00 C!
The camera should be stored in a dry environment with the temperature ranging from -
500 to + 900 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 to be cleaned, use soft lint free cloth and an optical cleaning
fluid. Do not use methylated alcohol!
2.3.4 Camera Link Full Signal Mapping
Camera data output is compliant with Deca (80-bit), Full (64-bit), Medium (48-bit) and
Base (24-bit) Camera Link standard and includes 12VDC Power over Camera Link (PoCL),
up to 80 data bits, 4 sync signals (LVAL, FVAL, DVAL and User Out), 1 reference clock, 2
external inputs CC1, CC2 and a bi-directional serial interface. The camera link output
connectors and corresponding bit and port mapping are described in the following Figures
and Tables.
