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.
Two reflecting surfaces perpendicular to each other are called ridge surface, and the prism with ridge surface is called ridge prism.
The ridge prism is small in volume and can make the objective lens and eyepiece in a straight line, so it is often used for extremely compact binocular lens.
The ridge prism can rotate and reverse the image and deflect light with a 90 ° bend. It is suitable for telescopes and any optical instrument that needs to flip the image from the objective lens, open the right side and bend at 90 ° to maintain the correct visual direction.
