Maintenance of external optical path optical lens

Avoid touching the surface of the optical lens (reflector, focusing lens, etc.) directly with your hands, as this can easily cause scratches on the mirror. If there are oil stains or dust on the mirror surface, clean it promptly to avoid affecting the lens’ performance.

Under no circumstances should the optical lens be cleaned with water and detergent as the lens’ surface is plated with a special film. Using water and detergent to clean the lens can damage its surface.

Keep the lens away from dark and humid environments as this can cause the lens surface to age.

Dust, dirt, or water vapor on the lens surface can easily absorb laser light and damage the lens coating, which can significantly affect the quality of the laser beam, and in severe cases, there would be no laser beam at all.

If the lens is damaged, contact the laser after-sales service department immediately to repair it. Avoid using the damaged lens, as this can accelerate the damage of the repairable lens.

When installing or replacing the reflector or focusing lens, avoid using excessive pressure, as it can cause deformation of the lens and affect the quality of the beam.

Steps for cleaning lens

Steps to Clean a Lens with a Cotton Swab:

Start by using a spray gun to blow off any dust on the mirror surface. Then, use a clean cotton swab to remove any remaining dirt.

Use a new cotton swab that has been moistened with high-purity alcohol or acetone. Gently move the swab in a circular motion from the center of the lens to scrub it. After each circle, use another clean cotton swab and repeat the process until the lens is completely clean. Never reuse a cotton swab that you have already used for cleaning.

Wash the lens with a clean cloth to remove any residue on the mirror surface. Be careful not to scratch the lens.

Take the cleaned lens to a place with sufficient light to observe its reflection. If the reflection is clear, it means the lens has been properly cleaned. If the reflection is not clear, continue cleaning the lens.

Finally, place the cleaned lens on a lens holder according to the appropriate method.
