Feature *18mm zinc selenide ZnSe lasers focusing lens focal length specification 50.8/ 63.5/101.6mm applicable power 50-180W *High light transmittance and high temperature resistance: The lens is made of CVD 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: CVD Zinc Selenide Design wavelength: 10.6um Diameter tolerance: ±0.1mm Thickness tolerance: ±0.13mm Focus tolerance: 90% Laser transmittance: 99.5% Focal length: ±2% Diameter: 18mm Focal length: 50.8/ 63.5/101.6mm (optional) Applicable power: 50-180W Scope of application: CO2 laser cutting machine Precautions 1. The focusing lens is installed with the convex surface facing upward. After replacing the lens it is necessary to fine-tune the lens barrel up and down and fix it in the best effect position. Second the use is to pay attention to the following points to prevent the lens from bursting and prolong the life of the lens. 1. The air-cooling failure of the machine causes the lens to overheat and burst or the air-cooling is not smooth and there is condensed water in the lens barrel which causes the lens to burst. 2. The anti-spray or liquid of the material to be engraved on the lens is easy to burst after being heated unevenly for a long time. It is necessary to use a cotton swab dipped in anhydrous alcohol to clean it in time. 3. When dimming the light path hits the edge of the lens and the junction of the lens barrel which is easy to cause bursting. Packing list: 1*laser focusing lens
