    Optical Elliptical window

    Elliptical 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,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.
    They are mainly used in medical equipment,digital camera, digital video recorders, , digital electronic windows and so on.
