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.
Color glass filter refers to the addition of special elements in the process of glass melting, so as to absorb different spectral bands and transmit the spectra of other bands. Due to the inherent absorption or transmission characteristics of the material, compared with the dielectric coated filter, the color glass filter will not change the central wavelength of the light beam incident at different incident angles.
