5.4.7.2 Mounting the Filter
Attention
It is recommended to have the filter changed under clean room conditions, otherwise dust might enter the sensor
area and become visible in images.
When completely removing the adjustment ring and the filter glass, the rubber gasket should also be removed. Due
to expansion of the rubber gasket during installation, it's difficult to reinstall then the filter glass.
The threaded ring presses the filter glass on a rubber gasket. A properly mounted threaded ring will seal off the
sensor. The threaded ring is screwed into the adjusting ring from the front with a torque of 0.2 Nm.
Notes
A special tool is required for adjusting the threaded ring!
Some DCx camera models have a different design with a separate filter glass that is secured by two screws.
