Special Optical glass prism cube

Silicon (SI) single crystal is a chemically inert material with high hardness and insoluble in water. It has good light transmission performance in 1.2 - 7um band and 30-300 in far infrared band μ M also has good light transmission performance, which is not possessed by other infrared materials. Silicon (SI) single crystals are commonly used as 3 - 5 μ M medium wave infrared optical window and optical filter substrate. Because of its good thermal conductivity and low density, the material is often used to make laser mirrors and occasions sensitive to volume and weight. The silicon lens or window produced by our company adopts optical grade silicon single crystal, with diameter range of 5 ~ 260mm, surface accuracy of 40 / 20 and surface flatness of: λ/ 10@633nm (the ratio of lens thickness to diameter shall conform to the processing proportion).
