Embodiment Construction
[0020] The polarizer with optical film according to the present invention, wherein boron-doped nano-ZnS is sequentially formed on the optical glass or optical resin polarizer substrate 1-X o X Thin films, composite metal films of nano-silver and copper, and nano-ZnO, TiO 2 and BaO nanocomposite oxide film. Wherein, the boron-doped nano-ZnS 1-X o X The film is prepared by a chemical vapor deposition method with a thickness of 25-50nm; the composite metal film of nano-silver and copper is prepared by an arc ion plating method with a thickness of 10-20nm, wherein the mass ratio of silver to copper is 2: 1-3:1; the nanocomposite oxide film is obtained by magnetron sputtering, with a thickness of 50-100nm. as attached image 3 As shown, in the polarizer with optical film according to the present invention, the transmittance of polarized light in the spectral range of 450-550nm is higher than 90%, and the transmittance of polarized light in the spectral range of 550-700nm is hi...
