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.
