Filter glasses
A filter glass is part of the optical path of the camera. This glass is placed on a layer of silicone, to keep dust out of the camera,
but not glued. The conversion of C-mount to CS-mount (see section
) must be carried out carefully. Operating the
camera without a lens mount is not intended and can lead to dropping out of the filter glass and the entry of dust. . Do not use
compressed air to clean the camera as this could push dust into the camera. Distance from the flange to sensor is designed so
the optical distance is 17.526mm – 0.2mm.
