ABSTRACT:
Anisotropic multilayer thin-film coating that may be used in fabrication of various optical elements, such as polarizers, beam splitters, interference-polarizing light filters, polarizing mirrors, etc. The invention is aimed at creating a multilayer optically anisotropic structure, which contains at least one layer with high degree of anisotropy and perfect structure, whereas refraction indexes and thicknesses of all layers and their combination is selected according to the known law, determined by the purpose of the structure, such as to provide an interference extremum for at least one polarization of light. The technical result is the increase of effectiveness of transforming incident radiation, which corresponds to the functional purpose of the multilayer optically anisotropic structure, due to the high reproducible degree of amsotropy of at least one layer in the structure.
