从China供应商批发进口Bk7 Ge Meniscus Lens Concave Convex Lens — FOB条款

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. Meniscus lens is concave convex lens. The lens has an outer convex mirror and an inner concave mirror. If the outward radian is greater than the inward radian, the lens has a positive focal length and is used as a magnifying glass. Borisun optics technology provides meniscus lenses without coating and coated with IR3 antireflection film. Germanium (GE) substrates are suitable for infrared applications.
