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.
Plano concave cylindrical lens are usually used to convert collimated laser sources into linear light sources. Plano concave cylindrical lens are often used in beam expansion applications. Compared with spherical lenses, cylindrical lenses are more difficult to manufacture. The commonly used materials are UV fused quartz and h-k9l.
K9 plano concave cylindrical lens only diverges in one direction and has no divergence function in the other direction
K9 plano concave cylindrical lens can see the transmittance of near infrared (350-2000nm).
