Product Description
Attention
CO2 laser focal lens can be applied to CO2 laser engraving/cutting machines.
Generally, a laser machine needs 1 piece of focal lens and 3 reflective mirrors.
For engraving, it’s recommended to use the lens of focal length 38.1/50.8mm; for cutting, lenses of focal length 63.5/76.2/101.6mm are more commonly used.

How to clean CO2 laser lens?
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 optic's surface. Using an eyedropper, squeeze a few drops of acetone onto the lens tissue, wetting the complete optic's 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 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.
