Definitions
- the invention relates to the surfacing of optical surfaces.
- Surfacing means any operation to modify the surface condition of a previously shaped optical surface. These include polishing, grinding or etching operations to modify (decrease or increase) the roughness of the optical surface and / or to reduce the undulation.
- a tool for surfacing an optical surface which comprises a rigid support having a transverse end surface, an elastically compressible interface which is applied against and covers said end surface, and a flexible pad adapted to be applied against the optical surface and which is applied against and at least partially covers the interface opposite and to the right of said end surface.
- the tool In order to reduce the roughness of the optical surface, the tool is brought into contact with the latter while maintaining sufficient tool pressure on it so that, by deformation of the interface, the pad conforms to the shape of the optical surface. .
- the optical surface is rotated, its friction against the tool being sufficient to jointly drive it in rotation.
- the surfacing operation requires an abrasive that can be contained in the buffer or in the fluid.
- the elastically compressible interface makes it possible to compensate for the difference in curvature between the end surface of the tool support and the optical surface, so that the same tool is suitable for a range of surfaces. optical curvatures and different shapes.
- the French patent application 2,834,662 proposes such a surfacing tool which, while being adapted to a range of optical surfaces sufficiently large, in terms of curvatures (convexity, concavity ) and shapes (spherical, toric, aspherical, progressive or any combination thereof, or more generally "freeform"), has good stability during surfacing, and allows surfacing at once safe, fast and good quality.

- this ring 17 is of circular longitudinal section, but it could also be of more complex section, in particular oblong, polygonal, rectangular or square. Furthermore, it is arranged on the peripheral part 16 concentrically with the support 4. The return means 15 are now described.
- These comprise at least one elastically flexible strip 18 which projects transversely from the support 4 and which is connected, on the one hand, rigidly to the support 4 by a first end 18a and, on the other hand, to the peripheral portion 14 of the buffer 6 by a second end 18b, said free end, opposite the first 18a.
- the return means 15 comprise a plurality of such strips 18 distributed uniformly around the periphery of the support 4, to act on the entire peripheral portion 14 of the buffer 6.
