Single side antireflection (AR) optical window
In the single side antireflection (AR) optical window, the antireflection enhances the transmitted light. The film that enhances the reflected light is called antireflection film. Its principle is based on the interference theory of light on the wave film. When the incident light strikes the surface of the dielectric film, changing the thickness of the dielectric film will strengthen or weaken the two columns of reflected coherent light generated by the incident light. When the interference of the reflected coherent light is maximum, the energy of the transmitted light is the smallest, and this kind of film is the antireflection film. When the reflected coherent light is the interference pole, the energy of the transmitted light is the strongest, and this kind of film is the antireflection film.
It is mainly used in LED display screen, instrument window, monitor protective mirror, mobile phone window, etc. Instrument window, fingerprint analyzer window, monitor protective mirror, mobile phone window, tablet computer window, window protection mirror, antique frame window, high-end watch window, glasses screen printing optical glass products.
