Abstract: A tool for surface treatment of an optical surface, includes a rigid support having a transverse end surface, an elastically compressible interface which is applied against and overlaps the end surface, and a soft buffer designed to be applied against the optical surface and which is pressed against and overlaps at least partly the interface opposite and perpendicular to the end surface. The buffer includes a so-called central part which is located between the end surface and a so-called peripheral part which is located transversely beyond the end surface, elastic return elements connecting the peripheral part to the support.

Abstract: A tool for polishing an optical surface of a lens includes a rigid support including a support surface, a first layer called the buffer made from an elastic material and covering at least part of the support surface, and a second layer called the polisher and covering at least part of the buffer. The buffer has a first surface adhering to the support surface and a second surface opposite the first surface. The polisher has a first surface adhering to the second surface of the buffer and a second surface called the polishing surface opposite the first surface and adapted to polish the optical surface of the lens by rubbing against it. The polishing surface is a toric surface and, to be able to polish an atoric optical surface, the buffer is adapted to be compressed elastically and the polisher is adapted to be deformed to espouse the atoric surface. Applications include polishing atoric optical surfaces.
