(EN) SEMI-FINISHED LENS, METHOD AND DEVICE FOR MANUFACTURING AN OPTICAL LENS
(FR) LENTILLE SEMI-FINIE, PROCÉDÉ ET DISPOSITIF PERMETTANT DE FABRIQUER UNE LENTILLE OPTIQUE
Abstract
(EN)
The invention concerns a semi-finished lens (10) comprising a first optical surface (12) comprising a surface design associated with a first reference system and a second optical surface (14) to be manufactured, the first and second optical surfaces are connected by an external periphery surface (16), the semi-finished lens further comprising a reference element (20) provided on the second optical surface (14) and/or on the external periphery surface (16), the position of the reference element (20) being defined with respect to the first reference system. The invention also relates to a method and a device for manufacturing an optical lens from such a semi-finished lens.

L'invention concerne une lentille semi-finie (10) comprenant une première surface optique (12) comprenant une conception de surface associée à un premier système de référence et une seconde surface optique (14) à fabriquer, les première et seconde surfaces optiques étant reliées par une surface périphérique externe (16), la lentille semi-finie comprenant en outre un élément de référence (20) disposé sur la seconde surface optique (14) et/ou sur la surface périphérique externe (16), la position de l'élément de référence (20) étant définie par rapport au premier système de référence. L'invention se rapporte également à un procédé et à un dispositif permettant de fabriquer une lentille optique à partir d'une telle lentille semi-finie.
