λ/4 Visible Windows

Optical Windows are flat plane-parallel plates, which are often used to protect electronic sensors or detectors without blocking optical transmission. Optical Windows do not change the magnification of a system. Grand Unified Optics offers a variety of optical windows, which cover the wavelength range from ultraviolet (UV) to infrared (IR).
