Title (EN) METHOD FOR MANUFACTURING AN OPTICAL ARTICLE
(FR) PROCÉDÉ DE FABRICATION D'UN ARTICLE OPTIQUE
Abstract:
(EN) The invention relates to a Method for manufacturing an optical article comprising the following steps: a. Providing a first substrate (14) with a main surface, b. Depositing a second substrate (16) on said main surface by means of an adhesive layer (15) so that the space between the first substrate (14) and second substrate (16) is filled by said adhesive layer (15), c. Curing the adhesive layer (15) to induce a polymerization of the adhesive layer (15), Wherein a tension step takes place after steps a. and b., and before step c, said tension step consisting in applying symmetrically a tension, preferentially with a central symmetry, preferentially a radial isotropic tension or an ortho- distributed symmetrical tension, on the edges of the second substrate (16) sensibly in a tension plan parallel to a plan representative of the main surface.
(FR) L'invention concerne un procédé de fabrication d'un article optique comprenant les étapes suivantes, consistant à : a. utiliser un premier substrat (14) pourvu d'une surface principale, b. déposer un deuxième substrat (16) sur ladite surface principale au moyen d'une couche adhésive (15) de telle sorte que l'espace entre le premier substrat (14) et le deuxième substrat (16) est rempli par ladite couche adhésive (15), c. durcir la couche adhésive (15) pour induire une polymérisation de la couche adhésive (15), une étape de tension ayant lieu après les étapes a. et b. et avant l'étape c., ladite étape de tension consistant à appliquer, de manière symétrique, une tension, préférentiellement avec une symétrie centrale, préférentiellement une tension isotrope radiale ou une tension symétrique distribuée en position ortho sur les bords du deuxième substrat (16) sensiblement dans un plan de tension parallèle à un plan représentatif de la surface principale.
