Optical window crystals are crystalline materials used as optical media. They are mainly used to make ultraviolet and infrared windows, lenses, and prisms. According to their crystal structure, they can be divided into single crystals and polycrystals. Due to their high crystal integrity, light transmittance, and low input loss, single crystals are the main optical crystals commonly used. OST Photonics produces a variety of optical window crystals, such as BaF2, CaF2, MgF2, LiF, Germanium, Sapphire, YAG, ZnSe, Silicon, ZnS, etc.
The optical window materials include various optical glass, UV fused silica, IR fused silica and functional crystal materials such as BaF2, CaF2, MgF2, LiF, Germanium, Sapphire, YAG, ZnSe, Silicon, ZnS, etc.
An optical window is one of the basic optical components in optics. It is an optical plate that protects electronic components, sensors, and semiconductor components in the optical path. The optical window does not change the magnification of the optics but only affects the optical path. Parameters such as transmittance, surface flatness, surface quality, thickness, parallelism, and material are important for selecting appropriate windows for specific applications.
Optical polycrystalline materials are mainly obtained through the hot pressing sintering process, including oxide, fluoride and semiconductor polycrystalline materials.
