CLEANING OPTICAL COMPONENTS PAGE | 71
• Always place optics lens on a tissue or suitable equivalent material for protection; never place
optics on hard or rough surfaces.
• It may be necessary to use a cotton ball or fluffed cotton swab instead of a lens wipe to uniformly
clean the entire surface of small-diameter mounted optics.
•
Before using any cleaning agents, read Material Safety Data Sheets (MSDS) and observe all
necessary safety precautions.
Required cleaning materials
The table below lists the type and grade of materials required to properly clean optical surfaces.
Table 4-1 Required cleaning materials.
Cleaning Material Requirements
Latex gloves or finger cots Powder-free
Air bulb Clean air bulb
Ethyl or isopropyl alcohol Spectroscopic or reagent grade
Acetone Spectroscopic or reagent grade
Lens wipe (preferred) Optical (clean room) quality
Cotton balls or cotton swabs High-quality surgical cotton/high-quality paper-bodied
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 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.
Important Note: Exercise great care when handling infrared optics; they are much more fragile
than common glass materials. Optical surfaces and coatings are easily damaged by rough
Caution: Possible Equipment Damage
Do not allow the nozzle of the air bulb to touch the optical surface. Any contact may damage the
optic by scratching coatings on the optical surface.
Do not use compressed shop air to blow contamination from the optic. Compressed air contains
significant amounts of water and oil that form adsorbing films on the optical surface.
Do not exert pressure on the surface of the optic during cleaning. Optical surfaces and coatings are
easily scratched by dislodged contaminants.
Use a new lens wipe on each pass as contaminants picked up by the wipe may scratch the optical
surface
