10.1 Optical System

The internal optical components of the camera should always be protected. If no
lens, or TV adapter with optics, is screwed into the camera's C-Mount thread, the
camera's sensor and IR-filter must be protected by screwing the protective cap
onto the camera's C-Mount thread.

10.2 Cleaning the infrared filter or protective glass

Contamination of the IR filter or the protective glass has an adverse effect on the
quality of the resulting image (dark points, cloudy structures in the image). If there
is dry dust on the front side of the infrared filter or protective glass, you can remove
it with a soft brush or with cotton (wool). Use cleaning fluid for optics/lenses only
to clean the IR filter. Do not use tap water to clean the IR filter.
