10.5 Lens Maintenance
Never touch the inner optics of the lens with your ngers. Keep the inner
optics perfectly clean with air, a lens brush or the dry cloth delivered
with the lens.
Do not touch the contacts. Keep the contacts clean with either a dry
cloth or by using a breglass brush. Do not use any other tools on the
lens.
The lens is not waterproof. It should be immediately dried with a cloth
if becomes wet. If it is exposed to salt, moisten a cloth, wring it and
carefully clean.
10.6 Back Maintenance
Cleaning the CCD
The Phase One IQ back must have the protection plate tted when
it is not attached to a camera. Dust may accumulate on the IR lter,
which will degrade the image quality if not removed. Please follow the
directions included in the CCD cleaning kit that came with the IQ back.
10.7 IR Filter on the CCD
The IR lter (Infrared reduction lter) is permanently mounted on top of
the CCD. The lter may not be removed for several reasons:
The focusing of the IQ back camera back will be damaged
It is only possible to remount the lter without dust getting in between
the lter and the CCD if you have access to special clean room facilities
The Phase One Product Warranty is terminated
