CO2 Laser Focus Lens Material: PVD ZnSeDiameter: 12 15 18 19.05 20mmFocal Length: 38.1 50.8 63.5 76.2 101.6mm Features: High transmittance: Made of high-quality zinc selenide (ZnSe) material, the transmittance is as high as 99.5%, ensuring efficient transmission of laser energy and improving processing efficiency. Precise focusing: A variety of focal lengths are available (1.5 inches, 2 inches, 4 inches, etc.) to meet different processing needs. Short focal length is suitable for fine processing, while long focal length is more suitable for cutting thick materials. High temperature resistance: The surface of the lens is coated with a heat-resistant anti-reflective film layer, which can work for a long time under high-power laser and extend the service life. Low absorption rate: The optical design is optimized to ensure minimum laser energy loss and reduce the risk of lens overheating. Easy to maintain: The surface is smooth, easy to clean and maintain, ensuring long-term efficien
