Thin dielectric films with different refractive indices are coated in multiple layers, and light interference is used to allow the selection of transmission or reflection of light from a light source at the desired wavelengths.
The number of layers of thin dielectric film coated can be from a few to several hundred, which allows various characteristics to be realized.
The shape of the substrate to be coated can be anything from flat to a parabolic mirror.
Lamp reflectors.
This mirror can be applied to various fields, including laser processing machines.
This is known generally as AR (anti-reflection).
It is a coating process in which a thin dielectric film is formed on the surface of a substrate in a single layer or multiple layers, and the reflectivity of the surface is reduced by light interference.
This increases the transmittance of the substrate, eliminates reflection on the surface and prevents ghosting.
The band of the anti-reflection effect can be selected by manipulating the thickness of the film, the number of layers and the combination of materials.
A wide range of wavelengths is available, from ultraviolet to infrared.
And a wide range of materials can be coated, including glass and infrared crystal materials.
Provides coatings on glass, resin, quartz, sapphire, ruby, YAG, Si, Ge, ZnSe, ZnS, etc. and other optical crystals.
Various cover glasses, prevention of ghosting on assembled lenses, sensor windows, etc.
Example applications include coating on curved lens surfaces, fiber end surfaces, cover glass surfaces, and crystal materials (CaF2, Si, Zn, Se).
