Optical Windows piece is one of the basic optical components in optics and is an optical plate that acts to protect the electronic component/sensor/semiconductor component in the optical path. The window does not change the optical magnification and only affects the optical path in the optical path. Mechanical properties such as light transmittance, surface accuracy, thickness, parallelism, and substrate material are important parameters of the window. MAP Opitcs offers high-precision windows in a variety of materials, including germanium (Ge), silicon (Si), N-BK7, UV fused silica, zinc selenide (ZnSe), barium fluoride (BaF2), calcium fluoride. (CaF2), potassium bromide (KBr), K9 window, and the like. Our multiple optional AR coatings can be used in applications such as UV, visible or infrared spectroscopy. We mainly tailor the optical window to your specific needs.
