Laser Mirror For 40W-150W Machine CO2 Laser Focus Lenses For Engraver Machine D25 F50.8/ 63.5/ 76.2/ 101 Laser Cutting Engraving Lens This should leave no streaks. 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 Step 3 Cleaning for Moderate Contamination (spittle, oils) Dampen an unused cotton swab or cotton ball with white distilled vinegar. Laser Focus Lens | CO2 Laser Optics | EFR Immediately dampen a cotton swab or cotton ball with acetone. Wipe excess distilled vinegar with a clean dry cotton swab. 5. Double-sided Solid Coating, demonstrates superior CO2 laser transmittance and is employed as the transmission optical components used in CO2 laser processing When install the Lens, Make Sure the Focal Lens: Convex Face to Laser, Concave Face to Material., Notice: 1., Make sure the optical path is corrected; 2., Remember to turn on the air pump when working; 3., Make sure the lens is clean and free from condensation. Using an eyedropper, squeeze a few drops of acetone onto the lens tissue, wetting the complete optic's diameter.
