Title (EN) A METHOD OF PRODUCING AN OPTICAL DEVICE AND A CORRESPONDING SYSTEM
(FR) PROCÉDÉ DE PRODUCTION D'UN DISPOSITIF OPTIQUE ET SYSTÈME CORRESPONDANT
Abstract:
(EN) A method of producing an optical device from a volume of a curable composition (4), comprises the following steps: - polymerizing a first portion (14) of said volume (4) by irradiating an external surface of said volume with a light irradiation (B), thereby increasing a transmittance of said first portion (14) for said light irradiation; - polymerizing a second portion of said volume by irradiating said second portion with said light irradiation (B) through said external surface and the polymerized first portion (14), wherein said light irradiation (B) has a light intensity varying over said external surface between a first light intensity and a second light intensity distinct from said second light intensity. A corresponding system is also described.
(FR) La présente invention concerne un procédé de production d'un dispositif optique à partir d'un volume d'une composition durcissable (4), qui comprend les étapes suivantes : - polymérisation d'une première partie (14) dudit volume (4) par exposition d'une surface externe dudit volume à une exposition lumineuse (B), ce qui permet d'augmenter la transmittance de ladite première partie (14) pour ladite exposition lumineuse ; - la polymérisation d'une seconde partie dudit volume par exposition de ladite seconde partie à ladite exposition lumineuse (B) à travers ladite surface externe et la première partie polymérisée (14), ladite exposition lumineuse (B) ayant une intensité de lumière variant sur ladite surface externe entre une première intensité de lumière et une seconde intensité de lumière distincte de ladite seconde intensité de lumière. L'invention concerne également un système correspondant.
