Instructions for cleaning lenses and protective glasses
Warning:
The laser beam can cause severe injury to the eyes and the skin. Before clean-
ing, make sure that the laser device is switched off and secured against acci-
dentally being switched on.
Fingerprints contain aggressive substances that can damage the optical surfaces. Optical
surfaces should therefore only be touched when wearing suitable gloves or with a lens clean-
ing cloth.
o
Only touch the optical elements when wearing suitable cotton gloves and only touch the
edges.
o
Blow loose particles from the surface with clean and oil-free compressed air. Note that the
compressed air in workshops can contain oil particles and is therefore unsuitable for clean-
ing the optical system.
o
Moisten a suitable lens cleaning cloth with ethanol suitable for cleaning optical compo-
nents.
o
Place one end of the moistened cloth on the optical system and slowly move it over the
optical components. Do not exert any pressure and do not rub the optical components.
o
Remove any remaining ethanol residue with a dry optical cloth.
o
Repeat the procedure until the surface is completely clean. Use a new cleaning cloth for
each repetition.

Instructions for cleaning mirrors
Warning:
The laser beam can cause severe injury to the eyes and the skin. Before clean-
ing, make sure that the laser device is switched off and secured against acci-
dentally being switched on.
The mirror surfaces are extremely sensitive and may only be cleaned by experienced person-
nel. We strongly recommend sending the deflection unit in to RAYLASE for the mirror clean-
ing, as opening of the deflection unit by unauthorized personnel voids the warranty.
However, if you want to clean the mirrors by yourself, follow the same procedure as for clean-
ing the lens but with even more care (
