The invention concerns a tool for surface treatment (1) of an optical surface (2), comprising a rigid support (4) having a transverse end surface (13), an elastically compressible interface (5) which is applied against and overlaps said end surface (13), and a soft buffer (6) designed to be applied against the optical surface (2) and which is pressed against and overlaps at least partly the interface (5) opposite and perpendicular to said end surface (13). The invention is characterized in that the buffer includes a so-called central part (6a) which is located between said end surface (13) and a so-called peripheral part (14) which is located transversely beyond said end surface (13), elastic return means (15) connecting said peripheral part (14) to the support (4).
Outil de surfaçage (1) d'une surface optique (2), qui comporte un support rigide (4) présentant une surface transversale (13) d'extrémité, une interface élastiquement compressible (5) qui est appliquée contre et recouvre ladite surface d'extrémité (13), ainsi qu'un tampon (6) souple apte à être appliqué contre la surface optique (2) et qui est appliqué contre et recouvre au moins en partie l'interface (5) à l'opposé et au droit de ladite surface d'extrémité (13). Suivant l'invention, le tampon comporte une partie dite centrale (6a) qui se trouve au droit de ladite surface d'extrémité (13) et une partie dite périphérique (14) qui se trouve transversalement au-delà de ladite surface d'extrémité (13), des moyens de rappel élastique (15) raccordant cette partie périphérique (14) au support (4).
