5 It may be necessary to use a fluffed cotton swab or cotton ball instead of a lens wipe to uniformly
clean the entire surface of small-diameter mounted optics.
6 Before using cleaning agents, read Material Safety Data Sheets (MSDS) and observe all necessary
safety precautions.
Required cleaning materials
Table 4-1 lists the type and grade of materials required to properly clean optical surfaces.

Cleaning optics
1 Shut off and lock out all power to the laser. You must verify that the laser is OFF (in a
zero-energy state) before continuing with the optical inspection!
2 Visually inspect all optical surfaces in the beam path, including the laser’s output coupler,
for contaminants.
3 Remove loose contaminants from the optic by holding a clean air bulb at an angle to the
optic and blow a stream of air at a glancing angle across the lens surface. Repeat, as
necessary.
4 Dampen a lens wipe with the selected cleaning agent. Alcohol (least aggressive) is best
for initial surface cleaning. Acetone (moderately aggressive) is best for oily residue or
minor baked-on vapor and debris.
Important Note: If acetone is used as a cleaning solvent, a second follow-up cleaning of the
optical surface using alcohol is required to remove any acetone residue.
