Startnow CO2 Laser Focus Lens China PVD ZnSe 12 18 19.05 20mm F38.1 50.8 63.5 76.2

CO2 Laser Focus Lens

Material: PVD ZnSe
Diameter: 12 15 18 19.05 20mm
Focal Length: 38.1 50.8 63.5 76.2 101.6mm

Features：

1. 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.
2. 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.
3. 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.
4. Low absorption rate: The optical design is optimized to ensure minimum laser energy loss and reduce the risk of lens overheating.
5. Easy to maintain: The surface is smooth, easy to clean and maintain, ensuring long-term efficient and stable laser processing effect
