China Optical Windows Manufactures
Optical windows are vital components in optical systems. They are used to isolate different environments while allowing light to pass through.
Unlike lenses, they do not alter the magnification or focus of the optical path, but instead serve as protective barriers with excellent transmission properties. Materials such as fused silica, sapphire, silicon, germanium, and magnesium fluoride. The optical windows can cover a wide spectral range from ultraviolet (UV), visible (VIS), to infrared (IR).
