  • Optical article having directional micro- or nanostructured thin film coating, and its process
    Patent number: 11867876
    Abstract: An optical article includes a substrate with front and rear main faces, one main face coated with a columnar micro- or nano-structured coating. The substrate and optical article are transparent in at least a part of the visible region ranging from 380 to 780 nm, along at least one incidence angle. The columnar micro- or nano-structured coating includes an array of columns including each a core and an upper layer covering the core, the core and the upper layer being structurally and/or chemically different and have light absorbing properties with an extinction coefficient “k” ?10-2 in the spectrum 250-2500 nm and are able to cause a change in transmission or in reflection of incident light through the optical article as a function of the angle of incidence of light. Also disclosed is a method for manufacturing an optical article including a columnar micro- or nano-structured coating.
