Standard Window
Optical Standard Windows are precision-engineered from high-grade optical glass and crystals, ideal for research, laser systems, and industrial applications. Superior light transmission, low scatter, and high durability. Custom sizes & coatings available. ISO-certified quality for unmatched optical performance! The window is a parallel flat panel that does not change the magnification of the system. The substrate material includes various optical glasses, ultraviolet fused silica, infrared fused silica, and crystal materials such as CaF2, MgF2, ZnSe, Ge, Si, and various optical coatings such as anti-reflection film, high reflection film, spectroscopic film, and metal film. Widely used in optical systems, usually as a protective device between sophisticated electronic equipment and the environment
