Visible light window glass is a parallel plane plate, usually used as a protective window for electronic sensors or detectors of the external environment.

When selecting a window, attention should be paid to the material, transmittance and transmission band, surface shape, finish, parallelism and other parameters of the window. Visible light window is a window designed for the visible spectrum. Visible light window is designed to prevent electronic sensors, detectors or other sensitive optical components from being saturated or suffering from light damage. Visible light window is suitable for imaging systems or as a protective display for various industrial or environmental applications. Visible light window does not change the magnification in the system.
The window can be made of quartz material/conventional series material such as K9 zf series, etc., or sapphire material, and the best choice is made according to different use conditions.
