Abstract

Outil de polissage d'une surface optique (3) d'une lentille (1), ledit outil (5) comportant :
  • un support (6) rigide comprenant une surface de support (8) ;
  • une première couche (9), dite tampon, réalisée dans un matériau élastique, qui recouvre au moins en partie la surface de support (8) du support (6) ;
  • une deuxième couche (10), dite polissoir, recouvrant au moins en partie le tampon (9), et présentant une surface de polissage apte à polir la surface optique (3) de la lentille (1) par frottement contre celle-ci.
La surface de polissage (14) est de forme torique et, afin d'être en mesure de polir une surface optique (3) qui est atorique, le tampon (9) est adapté à être comprimé élastiquement, tandis que le polissoir (10) est adapté à être déformé pour épouser ladite surface optique (3).
Application au polissage de surfaces optiques atoriques.
