>> Product Description
Windows are optical glass with ground and polished faces that are relatively parallel. They are used to isolate two physical environments while allowing light to pass. When selecting windows, you should consider the following: material, transmission, scattering, wavefront distortion, parallelism, and resistance to a certain environment.
the optical window is optical glass with grinding and polished faces that are parallel to each other, windows can be a protection of original when it's in two physical environments. And there is almost no effect on visible light, to coat on the surface of windows could increase the transmittance, the commonly used coatings are antireflection coating (AR) and scratch-resistant coating(AS). Windows with coating can enhance the light penetration strength, and own function of waterproof, dustproof, and scratch-proof.
