Maintenance of Optics

5.2.1 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.

5.2.2 Supplies or Cleaning Optical Surfaces

• Soft camel-hair brush
• Dust-free blower - filtered dry nitrogen blown through an anti-static nozzle.
• Dust-free lens tissue, such as Melles Griot Kodak tissues (18LAB020), Opto-wipes (18LAB022), Kim
Wipes or equivalent
