Abstract
An apparatus for polishing an optical surface, in particular an optical surface of a spectacle lens, is disclosed. The apparatus comprises a polishing head having a polishing tool, the polishing tool being provided along a common axis, one behind another, with a first preferably rigid member, a second elastic member, and a polishing lining, each extending essentially radially relative to the axis. The second elastic member is configured to be increasingly soft in a radial outward direction. Moreover, a method of polishing an optical surface, in particular a surface of a spectacle lens, an optical component manufactured according to that method, in particular a spectacle lens, as well as a method of manufacturing a polishing tool are disclosed.
