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.
At 2-12μm In the range of M, germanium is the most commonly used material for optical lens and optical window in high-efficiency infrared imaging system. Germanium has a high refractive index in band with 2-14μm, It is about 4.0, and the characteristics of minimum surface curvature and small color difference usually do not need to be corrected in low-power imaging system.
