Attention: Double-sided solid coating,Wiping resistant,Extended durability,Precision slicing polishing and grinding processes,High temperature laser resistance,Excellent optical properties,High working efficiency. The MCWlaser CVD II-VI ZnSe Focus Lens is a high-quality lens designed for use with CO2 laser engravers and cutters. With a diameter of 28mm and a focal length of 3 76.2mm, this lens is perfect for use with laser machines that have a power output between 300W and 600W Normally, the laser lens of focal length 38., 1mm and 50., 8mm is suitable for engraving. Material: Hight class USA Imported II-VI CVD ZnSe material , Diameter: 28mm/1., 10 inch; Focal Length:76., 2mm/3 inch;Thickness:3., 5-4mm;Transmittance: ≥99., 8% If used for cutting, we suggest to work with the laser lens of focal length 63., 5/76., 2/101., 6/127mm Before replace or install the lens, please confirm the diameter and focal length firstly. (1) Ensure that the air cooling is good, otherwise the temperature will be too high and the lens will overheat and crack (2) There are condensation water drops in the lens barrel, which may cause the lens to break. It should be cleaned with cotton ball dipped in absolute alcohol or acetone in time. Application CO2 laser focus lens is used in CO2 laser engraving/cutting machines. Laser transmittance can be as high as 99., 8% CO2 Laser Focus Lens MCWlaser CVD II-VI ZnSe CO2 Laser Fokuslinse Durchmesser: 20 Mm FL: 2,5" Oder 63,5 Mm Laser Linse Lens Für CO2-Lasergravur Schneidgravierer/schneider 40W-200W CO2 Laser Lens (4) When adjusting the light path, the light path is not correct, the laser accidentally hit the edge of the lens and the junction of the lens barrel, resulting in broken.
