In the field of optics, in the optical glass or quartz surface plating a layer or several layers of different substances after the film, you can get a high reflection or non-reflective (i.e., increase the permeability of the film) or a certain proportion of the reflection or transmission of the material, but also to get to some wavelengths absorbed, and other wavelengths of the transmission of the color filters.
① reflection-reducing film, such as cameras, slide projectors, projectors, movie projectors, telescopes, scopes, and a variety of optical instruments, lenses and prisms coated with a single layer of MgF, thin film and double or multi-layer by the Si02, Al203, Ti02, and other thin films composed of broadband reflection-reducing film.
② reflective film, such as large-diameter astronomical telescopes, various types of lasers, as well as new buildings in the large window coated glass used in the high-reflective film.
③ Beamsplitters and filters, such as color printing and magnification equipment used in the red, green, blue three primary color filters plated on the multilayer film.
④ lighting light source used in the anti-heat mirror and cold mirror film.
⑤ Light control films and low reflection films used in buildings, automobiles and airplanes, such as Cr, Ti stainless steel Ag, Ti02-Ag-Ti02, and ITO films.
(6) Laser discs and optical storage films in the CD-ROM, such as Fe81Ge15SO2, magnetic semiconductor compound film, TeFeCo amorphous film.
(vii) Dielectric and semiconductor films used in integrated optical components and optical waveguides.
