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
