Description

How to Determine Focal Length? The Focal Length is the Distance Between the Focal Lens and the cutter/engraver Material. When install the Lens, Make Sure the Focal Lens: Convex Face to Laser, Concave Face to Material. How to Clean Laser Lens and Mirrors? 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. The difference between USA CVD and China PVD: The CO2 laser focal lens are made by USA CVD ZnSe. USA CVD can withstand higher power, and USA CVD has better focusing spot and better laser transmittance than China PVD.

  • Love this lens!
Size: Diam. 19.05mm / 0.75 in Color: FL: 50.8mm / 2 in
This lens was a perfect swap for my Gravotech LS100. Fit was perfect and I’m back to cutting and engraving as normal.

  • Works great
Size: Diam. 18mm / 0.71 in Color: Fl: 63.5mm / 2.5 in
Added this lens to my 80 watt laser to replace my 1.5 inch. Makes cutting through 1/4 in plywood a breeze without having to change my focus. Easy to swap out lenses as well.

  • Works just as well as other expensive lenses.
Size: Diam. 20mm / 0.79 in Color: Fl: 76.2mm / 3 in
Great quality, works just as well on my 80w as the much higher priced lenses.

  • Good lens, but you'll need to run a focus test first.

This lens performed well, once I ran a focus test. Would have been nice to have been sent a card with the focal parameters.
