Title
(EN) OPTICAL ARTICLE TO PROVIDE VISION CORRECTION FOR DEVICES USING EYE TRACKING DEVICE
(FR) ARTICLE OPTIQUE POUR FOURNIR UNE CORRECTION DE LA VISION POUR DES DISPOSITIFS UTILISANT UN DISPOSITIF DE SUIVI DE L'ŒIL
Abstract
(EN) The invention relates to an optical article comprising a transparent substrate with a front main face and with a rear main face, at least one of the main faces being coated with a multilayered interferential coating comprising a stack of at least one high refractive index layer (HI) having a refractive index higher than or equal to 1,55 and at least one low refractive index layer (LI) having a refractive index layer lower than 1,55, wherein said multilayered interferential coating has: ■ a mean light reflection factor in the visible region, noted R v, that is lower than or equal to 2,5% for at least an angle of incidence lower than or equal to 35°; ■ a mean reflection factor for wavelengths ranging from 800 nm to 900 nm, noted R m ET ( 800- 900), that is lower than or equal to 1,5% at an angle of incidence lower than or equal to 20°, characterized in that: • ■ said multilayered interferential coating has a mean reflection factor in the near infrared (NIR) region ranging from 900 nm to 2000 nm, noted R m NIR, that is higher than or equal to 11,5 % at an angle of incidence lower than or equal to 20° and/or said transparent substrate comprises at least one absorbing dye which absorbs in the near infrared region at a wavelength ranging from 900 to 2000 nm.
(FR) L'invention concerne un article optique comprenant un substrat transparent présentant une face principale avant et une face principale arrière, au moins une des faces principales étant revêtue d'un revêtement interférentiel multicouche comprenant un empilement d'au moins une couche à indice de réfraction élevé (HI) ayant un indice de réfraction supérieur ou égal à 1,55 et au moins une couche à faible indice de réfraction (LI) ayant une couche d'indice de réfraction inférieure à 1,55, ledit revêtement interférentiel multicouche ayant : un facteur moyen de réflexion de la lumière dans la région visible, noté Rv, qui est inférieur ou égal à 2,5 % pour au moins un angle d'incidence inférieur ou égal à 35°; un facteur de réflexion moyen pour des longueurs d'onde allant de 800 nm à 900 nm, noté Rm ET (800-900), qui est inférieur ou égal à 1,5 % selon un angle d'incidence inférieur ou égal à 20°, caractérisé en ce que : le revêtement interférentiel multicouche présente un facteur de réflexion moyen dans la région de proche infrarouge (NIR) allant de 900 nm à 2 000 nm, noté Rm NIR, qui est supérieur ou égal à 11,5 % selon un angle d'incidence inférieur ou égal à 20° et/ou ledit substrat transparent comprend au moins un colorant absorbant qui absorbe dans la région proche infrarouge à une longueur d'onde allant de 900 à 2 000 nm.
