Infrared Optics Catalogue
Cleaning
General:
All materials used for infrared optics are fragile - whether single industrial crystal or polycrystalline - large or fine grained. They are not as strong as glass and will not withstand procedures normally used on glass parts.
• Infrared optics should never be touched. Always wear powder-free finger cots or surgical professional gloves. Dirt and oil from the skin can severely contaminate optics, causing a major reduction in performance.
• Do not use any tools to handle optics.
• Always place optics on the lens tissue supplied for protection.
• Never place optics on a hard or rough surface. Infrared laser optics can be easily scratched.
• Bare gold or bare copper should never be cleaned or touched.
Note:
Except for Method 1, the cleaning procedures described here should not be used for new optics. New optics are cleaned and packaged prior to dispatch to ensure their high quality condition upon receipt. If you suspect a problem with contamination, or other cosmetic defects with a new optic, please contact Pleiger immediately.
Method 1 - Mild Cleaning for Light Contamination (dust, lint particles)
Use an air bulb to blow off any loose contaminants from the surface of the optic before proceeding to the cleaning steps. If this step does not remove the contamination, continue to Method 2.
Note:
Avoid using shop air lines because they usually contain significant amounts of oil and water. These contaminants can form detrimental absorbing films on optical surfaces.
Method 2 - Mild Cleaning for Light Contamination (smudges, fingerprints)
I. Dampen an unused cotton swab or a cotton ball with acetone or i-propanol.
II. Gently wipe the surface with the damp cotton. Do not rub hard.
III. Drag the cotton across the surface just fast enough so that the liquid evaporates right behind the cotton. This should leave no streaks. If this step does not remove the contamination, continue to Method 3.
Note:
• Use only paper-bodied cotton swabs and high-quality surgical cotton professional balls.
• Reagent grade acetone and i-propanol are recommended.
