Maintenance of Optics

5.3.1 Optical (Excluding Lens)

Unnecessary cleaning of optics, increases the risk of degrading delicate coatings and surfaces. Only clean
optics when dust, dirt, oil, fingerprints or other marks are obvious and are causing performance problems.
Maintenance of optical components requires a qualified service technician. Inspect exposed optical surfaces
periodically in a clean, dust-free environment using a flashlight. Never touch an optical surface with your bare
hands. Always wear latex lab gloves.
