Featuring a 20mm diameter and a durable gold-plated coating with protective film, it delivers superior reflection efficiency and long service life. Sold as a set of three mirrors, it significantly enhances laser cutting and engraving performance, making it a must-have upgrade for professionals seeking flawless results and reliability. ## Description Product description Attention The reflective lens can be applied to CO2 laser engraving/cutting machines and is used for planar reflecting the laser beam. Generally, a laser machine needs 1 piece of focal lens and 3 reflective mirrors. This mirror is coated with a protective film on the gold layer after gold plating to protect the gold layer from damage and improve reflection. It is suit for the laser machine of power below 50W. As for machine with power above 50W, the mirrors of molybdenum or gold-plated silicon are more appropriate. Please confirm the diameter of lens that you need. Product Details - K9 Gold-Plated Glass Reflective Lens 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. Review: Good stuff - Bought a k40 at auction, didn't really know what to expect. One of the mirrors shattered (!) because it wasn't in great shape when I got it (must have taken too much heat). Couldn't cut through Luan before, 10mm/s 5 passes, just charred and never separated. These mirrors, same speed, one pass, all the way through. I don't know how it compares to stock mirrors in good shape, but they definitely get the job done now! Review: i don't trust ten-high anymore - actually the mirrors are working ok. But i got burned so bad on their cloudy lens I will never give them a good rating. ## Features - Diameter: 20mm/0.79"; Thickness: 3mm/0.19"; Weight: 0.2KG - Material: K9 Gold-Plated Glass; Compatible power: 40W-50W - Shape: Plane; Transmittance: ＞99.8% - 【High Quality】Superb coating art, precision slicing, polishing and grinding.
