China Zns Plano Concave Lens Optical Laser Lens

CO2 laser focusing lens is widely used in laser processing for , cutting, drilling, sculpture, engraving etc and laser systems. To meet the market's need, we explored the following two series products: Plan-convex and Plano-concave mirror and crescent lens.

ZnSe and ZnS are crucial materials for IR optics due to their transparency in a broad spectral region from 0.4 to 20 mkm. Since the moment of its foundation NN OPTIKA company has produced CVD ZnSe which is an ideal material for manufacturing optical components used in powerful industrial CO2 lasers. CVD ZnSe is also widely applied in thermal vision devices as well as in various IR maging systems, e.g. in medical instruments. As for ZnS, it is mainly used in IR spectrometers and some kinds of special equipment.
