Description

Attention

  1. The reflective lens can be applied to CO2 laser engraving/cutting machines and is used for planar reflecting the laser beam.
  2. Generally, a laser machine needs 1 piece of focal lens and 3 reflective mirrors.
  3. Made of Molybdenum, this type of material can be worked under high temperature and harsh environments, resistant to wipe. Precision slicing, polishing, grinding. Without coating, but has extremely tough surface and is more resistant to high temperature than silicon reflective lens.
  4. Please confirm the diameter of lens that you need.

How to clean CO2 laser lens?

Cleaning Step 1Cleaning Step 1

Cleaning Step 2Cleaning Step 2

Cleaning Step 3Cleaning Step 3

Step 1 - 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.

Step 2 - Cleaning for Light Contamination (smudges, fingerprints)

Lay the lens tissue on the optics surface. Using an eyedropper, squeeze a few drops of acetone onto the lens tissue, wetting the complete optics diameter. Without lifting the lens tissue, drag the lens tissue across the optic just fast enough so that the liquid evaporates behind the tissue. This should leave no streaks.

Step 3 - Cleaning for Moderate Contamination (spittle, oils)

Dampen an unused cotton swab or cotton ball with white distilled vinegar. Using light pressure, wipe the optics 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 optics surface to remove any acetic acid.
