Cleaning guidelines for removed optics.
The following outlines the proper procedure for cleaning optics that has been removed from the laser system. To prevent the inadvertent misalignment of the laser system optics should be installed cleaned in their mounts whenever possible.
Optic cleaning is not a required component of a regular laser system maintenance schedule. Optics should only be cleaned as a corrective action for marked power decrease or poor mode quality. Optics should not be cleaned unless signs of contamination are clearly visible on the optic surfaces. Unnecessary cleaning will only shorten the life span of the optical coating.
Optics and optic coatings can be easily chipped or scratched. Therefore, to prevent damage when removing or replacing mirrors, always grasp the optic by the outer edge. Never touch the optical surfaces with bare skin.
Handle laser optics with care. A scratch, trace of dirt, or film will diminish the laser’s efficiency. Always use finger cots, latex gloves, or the equivalent when handling optics, and use a clean, cushioned work surface.
