| 摘要 |
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).
