Structure: Meniscus
2. Product Description / 产品简介
ZnSe has been made by means of import CVD from USA, and this material has low absorbance.
The lens can can with stand 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 and have developed a series of products with the minimum actual focal spot diameter in the case of the same focal length. We can respectively design and produce the products according to different requirements of the customers for focus length, rear focus length, lens aperture, the diameter of the incident ray and so on.
