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.
Pyramid prism, also known as retroreflector, is a prism made of BK7 or UV fused silica. We can provide customized corner cube prisms of various sizes. The incident end face can be plated with AR film as required, and the reflecting surface can be plated with metal film.
Advantages of pyramid prism: the prism is not sensitive to the incident angle of incident light. When incident within a certain range of incident angle, the outgoing light or image will be reflected by 180 °. It is an ideal reflective optical element.
Disadvantages of pyramid prism: incident light and outgoing light will not overlap, and they will be staggered by a distance. After the reflected light passes through the pyramid prism, its polarization state will change.
Hanzhong Borisun Optics Co., Ltd. provides customized production of corner prism custom production.
