Visible windows(N-BK7 or H-K9L window) are parallel plane plates, usually used as protective windows for electronic sensors or detectors of the external environment.

When choosing a window, you should pay attention to the material, transmittance and transmission band, surface shape, finish, parallelism and other parameters of the window. Visible windows are designed for the visible spectrum. Visible windows are designed to prevent electronic sensors, detectors or other sensitive optical components from being saturated or suffering from light damage. Visible windows are suitable for imaging systems or as protective displays for various industrial or environmental applications. Visible windows do not change the magnification in the system.

AOS Optics provides without coating and coated services, double-sided broadband anti-reflection coating, which can reduce the reflectivity of the surface and enhance its transmittance. You can choose VIS (350-700nm), NIR (600-1100nm), SWIR (900-1700nm) anti-reflection.
