Focal Length 50, 8mm/63, 5mm/101mm Focus Lens for Cutting Machine

Diameter 25mm focal length 50,8mm/63,5mm/101mm focus lens for laser cutting machineFocus lens is widely used in laser CO2laser processing industry, including laser cutting, engraving, marking, drilling and other laser systems.GaAs laser focusing lens is widely used in laser processing, (cutting, drilling, welding, sculpture, etc.) and a variety of laser systems.ZnSe has been made by means of import CVD from USA, and this material has low absorbance. The lens can withstand high power density and the surface coating is solid , not easy to fall off and wipe-resistant. After AR-coating has been coated on double-side of imported ZnSe, the transmissivity of the wavelength 10.6um, which is commonly used in CO2 laser industry, can reach 99.5%.
