Abstract

Usually any anti-corrosion protective coating worsens to some extent the optical properties of the object. This is also related as well to Brewster-angle windows since the null reflectivity at the Brewster angle is a property of a flat interface between two lossless dielectrics, which can never be obtained with an isotropic film-covered substrate. It is possible, however, to design some specialized anisotropic coatings deposited onto the Brewster angle window which sustain exactly the position of the Brewster angle and a true zero of the reflection factor.
