Abstract

Composant optique (5) comprenant un substrat (6) en un matériau ayant un taux prédéterminé de transmission de rayonnements ayant une longueur d’onde comprise dans une bande prédéterminée de longueurs d’onde, et un revêtement (7) s’étendant sur une surface (6’) du substrat (6). Le revêtement (7) comprend une matrice (8) à base d’au moins un polymère dans laquelle sont noyées des nanoparticules (9), le composant optique (5) ayant au total un taux de transmission suffisant pour l’application pour des longueurs d’ondes comprises dans la bande prédéterminée de longueurs d’onde. FIGURE DE L’ABREGE : Fig. 2Optical component (5) comprising a substrate (6) made of a material having a predetermined rate of transmission of radiation having a wavelength comprised in a predetermined band of wavelengths, and a coating (7) extending over a surface (6') of the substrate (6). The coating (7) comprises a matrix (8) based on at least one polymer in which nanoparticles (9) are embedded, the optical component (5) having in total a transmission rate sufficient for the application for lengths of waves included in the predetermined band of wavelengths.
