Adaptable lapping disc for the fine machining of optical surfaces and a method for the fine machining of a selected optical surface with an adaptable lapping disc

摘要

Adaptable lapping disc (12) for the fine machining of optical surfaces, comprising:a rigid base (18), which defines a curve, a working surface (22) which, on the base surface (18) for making contact with a selected optical surface and with the curvature of the selected optical surface, anda selectively adjustable substance (24), which forms a layer, which extends between the rigid base (18) and of the working surface (22) and optionally extends between a solid and liquid state can change, wherein the substance (24) in its liquid state, a movement of the working surface (22) in relation to the surface area (18) is made possible in order to the curvature of the selected optical surface conforming to, and the substance (24) in the solid state, the working surface in a position in which, together with the curvature of the selected optical surface conforming, and this said conformal position during the fine machining of the selected optical surface is maintained, wherein the selective adaptable..
