Mduoduo Laser Focusing Lens CO2 Lasers Focusing Lens ZnSe Focal Lens Dia.19mm for Engraver Cutter Machine

Feature *19mm zinc selenide ZnSe lasers focusing lens focal length specification 50.8/ 63.5/101.6mm applicable power 50-100W *High light transmittance and high temperature resistance: The lens is made of PVD coded zinc (ZnSe) material with low lasers transmission loss low absorption strong light transmittance and light transmittance can be as high as 99.8% and can withstand high-power lasers * Coating is not easy to fall off and wipe-resistant: The enhanced double-sided coating process is adopted the coating is firm and not easy to fall off durable wipe-resistant and has a long service life * Thin spot and fast cutting speed: The cylindrical surface of the lens is polished which increases the amount of light transmission reduces or eliminates the stray light of the system improves the ability of the lens to withstand reflections and makes the lens s spot finer and the cutting speed is faster. *Complete specifications and wide application: complete types of lens specifications suitable for laser cutting machines and engraving machines of major brands Specification: Name: Laser Focusing Lenses Material: Zinc Selenide Diameter: 19mm Focal length: 50.8/ 63.5/101.6mm (optional) Applicable power: 50-100W Scope of application: CO2 laser cutting machine Packing list: 1*laser focusing lens
