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.
Quartz glass is an ideal UV material. It has high transmittance in the range of 220nm to 2500nm, good chemical stability and radiation resistance, low expansion coefficient, low fluorescence radiation and scratch resistance.
Optical window sheet is a parallel plane plate, which is usually used as a protective window for electronic sensors or detectors in the external environment.
When selecting a window sheet, the user should consider whether the transmission properties of the material and the mechanical properties of the substrate are consistent with the application requirements. The window slice does not change the magnification of the system.
