    Abstract: Tool (1) for planing an optical surface (2) has a rigid support (4) with an end transverse surface (13), an elastically compressible interface (5) that is applied against and covers the end surface and a flexible tampon (6) able to be applied against the optical surface and that is applied against and covers at least partially the interface that it opposes and to the right of the end surface. The tampon includes a central part (6a) found to the right of the end surface and a peripheral part (14) found transversely on the other side of the end surface where are provided an elastic spring (15) comprising, in order to link this peripheral part to the support, a flange (18) presenting a peripheral part (22) continuously co-operating in thrust with the peripheral part of the tampon.

    Abstract: The smoothing implement for optical lenses has a support (11) with an annular recess (15) to receive the smoothing tool (12) which is mounted by a smaller recess (16) in the floor of the main recess. The smoothing tool projects beyond the mounting. The implement has an elastic hub and projecting faces on the edges facing the smoothing tool to form an outlet orifice.

    Abstract: Il 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 appliqu é 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) tandis que sont prévus des moyens de rappel élastique (15) comportant, pour raccorder cette partie périphérique (14) au support (4), une collerette (18) présentant une partie périphérique (22) continue coopérant à appui avec ladite partie périphérique (14) dudit tampon (6).
