Imported ZnSe material focusing lens laser engraving machine dedicated for cutting machine
Dowin laser engraving machine cutting machine adopts imported focusing lens, which has high light transmittance, low reflection of double-sided anti-reflection coating, stable light spot, clean and scratch-resistant.
Infrared optical material, high purity, strong environmental adaptability, low loss, light transmittance up to 99.8%, and can withstand 200W laser power.

The lens has stable focusing, good cutting and engraving effect, can withstand high power density, and the surface film layer is firm and not easy to fall off, and is resistant to wiping.

The cylindrical surface of the lens is polished to increase the amount of light transmission, reduce or eliminate the stray light of the system, improve the ability of the lens to withstand returning light, make the lens spot thinner and the cutting speed faster.
