Optical properties and morphology of polarization coating based on the SiO$_2$ and ZrO$_2$ layers

The 7-layer polarization coating design based on SiO$_2$ and ZrO$_2$ layers deposited by electron beam evaporation onto substrates of various types has been developed. Determination of the effect of the nature of the substrate on the degree of polarization of the coating showed that the maximum degree of polarization of 0,75 transmitted radiation was achieved at an angle of incidence of 75$^\circ$ when spraying the coating on a substrate of polyethylene terephthalate. It was found that the polarization coating is characterized by low roughness values of 5,41 nm.
