Product Description

Carmanhaas Beam combiners are partial reflectors that combine two or more wavelengths of light:  one in transmission and one in reflection onto a single beam path. Commonly ZnSe beam combiners are optimally coated to transmit infrared Laser and reflect visible laser beam, as in combining infrared CO2 high-power laser beams and visible diode laser alignment beams.

Product Cleaning

Due to the problems encountered when cleaning mounted optics, it is recommended that the cleaning procedures described here be performed only on unmounted optics.
Step 1 – Mild Cleaning for Light Contamination (dust, lint particles)
Use an air bulb to blow off any loose contaminants from the optic surface before proceeding to the cleaning steps. If this step does not remove the contamination, continue to Step 2.
Step 2 – Mild Cleaning for Light Contamination (smudges, fingerprints)
Dampen an unused cotton swab or a cotton ball with acetone or isopropyl alcohol. Gently wipe the surface with the damp cotton. Do not rub hard. 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 Step 3.
Note: Use only paper-bodied 100% cotton swabs and high-quality surgical cotton balls.
Step 3 – Moderate Cleaning for Moderate Contamination (spittle, oils)
Dampen an unused cotton swab or cotton ball with white distilled vinegar. Using light pressure, wipe the optic’s surface with the damp cotton. Wipe excess distilled vinegar with a clean dry cotton swab. Immediately dampen a cotton swab or cotton ball with acetone. Gently wipe the optic’s surface to remove any acetic acid. If this step does not remove the contamination, continue to Step 4.
Note: Use only paper-bodied 100% cotton swabs.
Step 4 – Aggressive Cleaning for Severely Contaminated Optics (splatter)
Caution: Step 4 should NEVER be performed on new or unused laser optics. These steps are to be done only on optics that have become severely contaminated from use and have no acceptable results yielded from Steps 2 or 3 as previously noted.
If the thin-film coating is removed, the optic’s performance will be destroyed. A change in apparent color indicates the removal of the thin-film coating.
For severely contaminated and dirty optics, an optical polishing compound may need to be used to remove the absorbing contamination film from the optic.
Note：Contamination and damage types, such as metal splatter, pits, etc, cannot be removed. If the optic shows the contamination or damage mentioned, it will probably need to be replaced.
