Product Description
Optical windows are fundamental components in optics, used to separate environments—for example, isolating the interior of an instrument from the exterior to protect internal devices. They do not change optical magnification and only affect optical path length in the light path. Key parameters of optical windows include transmittance, surface accuracy, thickness, parallelism, and substrate material, which can be selected based on specific applications.
