2.8 Care and Cleaning of a NIRvana-LN System
From time to time, NIRvana-LN cameras may require minor cleaning.
WARNING!
Turn off all power to the equipment and secure all covers
before cleaning the units. Otherwise, damage to the equipment
or injury to you could occur.
2.8.1 Camera
Although there is no periodic maintenance that needs to be performed on a NIRvana-LN
camera, users are advised to wipe it down with a clean damp cloth from time to time. 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.
2.8.2 Optical Surfaces
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.
Pay extra attention if the optical window is coated with AR (anti-reflection) materials as
they can be susceptible to scratches. Please contact factory if you have any questions.
WARNING!
After cleaning optical surfaces using this method, verify that
all surfaces and components have dried completely before
applying power to the NIRvana-LN.
2.9 Repairs
The NIRvana-LN camera system contains no user-serviceable parts. Therefore, repairs must
be performed by Princeton Instruments. Should a system need repair, contact Princeton
Instruments customer support for instructions. For contact information, refer to

TIP:
Save all original packing materials for future use when it is
necessary to ship the system and/or system components.
