Abstract
Three-layer, low color purity, anti-reflection coatings reduce the reflection of visible light rays and display a low color purity when glazings carrying such coatings are oriented at high angles of incidence with respect to a source of visible light. The reflectances are comparable and the color purity values are lower for such glazings, when compared with conventional glazings coated with 1/4-178 -174 wavelength anti-reflection coatings.
