Hanzhong Brisun Optics Co., Ltd. Is the high High precision optical element manufacturer provides customized production of Various optical lenses, including spherical lens, cylindrical lens, optical window, mirror, prism, filter, metal base mirror and other high-precision optical elements. The base materials include various optical glass, fused quartz, calcium fluoride (CaF2), zinc selenide (ZnSe), germanium (GE), silicon (SI), sapphire, metal and other materials. And provide antireflective film, high reflection film, spectroscopic film, metal film and other optical coatings.
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 - 7μm band and 30-300 in far infrared band μm also has good light transmission performance, which is not possessed by other infrared materials.
Silicon (SI) single crystals are commonly used as 3 - 5μm medium wave infrared optical lens, 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.
