C645 camera back is not attached to a
CONTAX camera, the camera back shall be protected with the
protection plate. Still dust particles can stick to the IR filter.
This will degrade the image quality.

Cleaning between the CCD and the IR filter
Do not try to clean between the CCD and the IR filter!
The mounting of the IR filter is done at the factory in a high-
class clean room. This process is a very specialized process that
assures an extremely high quality of the glass surfaces of the
CCD and the IR filter. The screws for locking the IR filter are
sealed. If the seal is broken, Phase One will not guarantee for
any particles between the CCD and the IR filter.
