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%. We have optimized the design from two sides , diffraction and aberration have developed a series of products with minimum actual focal spot diameter in the case of the same focal length.
