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.
Spherical lens is an important optical element, which is mainly made of optical glass and other materials. It is used for the coupling between optical fibers, between laser and optical fiber, and between optical fiber and detector, or for the collimation of optical fiber beam in thin film filtered dense wavelength division multiplexer.
Spherical lens is also called glass bead. It is a solid or hollow glass bead with a diameter of several microns to tens of microns. Its application fields involve various departments such as chemical industry, aerospace, transportation, petroleum, light industry, medical treatment and so on. It has the characteristics of good surface finish, good light reflection, directional reflection, high impact strength, chemical stability, light bulk weight and so on.
