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.
One side of meniscus cylindrical lens is concave and the other side is convex. Its function is to make the beam converge or diverge to a plane, and the beam does not work in the vertical plane. Meniscus cylindrical mirror can convert transmitted plane wave into cylindrical wave or cylindrical wave into plane wave or spherical wave. This kind of lens can correct visual aberration. Moreover, the edge thickness is larger than the center thickness, which can limit the reduction of spherical aberration. It is often used to combine with another lens to form an optical system, so as to reduce the numerical aperture. It is a common element in beam expansion applications.
