Title
(EN) POLARIZED LENSES OBTAINED BY THE LAMINATION OF A POLARIZED FILM
(FR) LENTILLES POLARISÉES OBTENUES PAR STRATIFICATION D'UN FILM POLARISÉ
Abstract
(EN)
The present invention relates to optical articles coupled to polarized laminate films. Optic properties, production methods, and compositions of component film layers were examined. Film layer criteria were selected that results in laminate films with particular optic properties. Lamination of optical elements with the inventive laminate films results in improved transmission and clarity through the optical elements.
(FR)
La présente invention concerne des articles optiques couplés à des films stratifiés polarisés. Des propriétés optiques, des procédés de production et des compositions de couches de film de composant ont été examinés. Des critères de couche de film ont été sélectionnés, permettant d'obtenir des films stratifiés dotés de propriétés optiques particulières. La stratification d'éléments optiques avec les films laminés inventifs se traduit par une transmission et une clarté améliorées à travers les éléments optiques.
