Cleaning and Maintenance

Cleaning the Camera

Although there is no periodic maintenance that must be performed on the PI-MAX3
Camera, users are advised to wipe it down with a clean damp cloth from time to time.
Note: The cloth should be just damp enough to pick up dust – not wet.
This operation should only be done on the external surfaces and with all covers secured.
In dampening the cloth, use clean water only. No soap, solvents or abrasives should be
used. Not only are they not required, but they could damage the finish of the surfaces on
which they are used.
Cleaning Optical Surfaces – Unigen
For greater sensitivity, the PI-MAX3 camera with Unigen II coating comes without a
protective window over the intensifier. Do not scratch the image intensifier's coated
surface. To remove any lint or dust use very clean dry nitrogen with < 5 PSI pressure. If
you have any questions please contact your sales contact or the factory.
Cleaning Optical Surfaces – Protective Window
Optical surfaces may need to be cleaned due to the accumulation of atmospheric dust. We
advise that the drag-wipe technique be used. This involves dipping a clean cellulose lens
tissue into clean anhydrous methanol, and then dragging the dampened tissue over the optical
surface to be cleaned. Do not allow any other material to touch the optical surfaces.

Flushing and Refilling the CCD Chamber

Under normal conditions the CCD chamber is sealed and backfilled so there is no danger
!

of damage due to condensation.
Operating an Intensified PI-MAX3 that is no longer backfilled with dry air or dry
!
WARNING
nitrogen may result in condensation on the array that could cause irreversible damage.
Such damage would not be covered by the Warranty.
Before a PI-MAX3 camera leaves the factory, its CCD chamber is backfilled with clean
dry air or dry nitrogen. For proper operation it is essential that the integrity of the front
enclosure be maintained.
In normal operation, the CCD chamber should remain sealed for the life of the detector
and should require no maintenance to assure integrity. If it should ever happen that the
CCD chamber becomes unsealed, contact the factory and arrange to return the detector to
the factory where it can be properly flushed, backfilled and resealed again. See page 146
for contact information.

Repairs

Save the original packing materials. Because the PI-MAX3 system contains no user-
serviceable parts, repairs must be done by Princeton Instruments. Should your system
need repair, contact Princeton Instruments customer support for instructions (telephone,
e-mail, and address information are provided on page 146 of this manual).
Use the original packing materials whenever shipping the system or system components.
