摘要： A set of eyeglass lens semifinished products is provided and is composed of at least three series of eyeglass lens semifinished products having spherical or rotationally symmetric aspherical front surfaces. The series of eyeglass lens semifinished products differ in pairs in the base material of the series. Each of the series includes at least three types of eyeglass lens semifinished products which differ in pairs and the front surface shapes. The front surface shapes of the at least three types are identical on a central partial surface within the actual surface refractive power range of the front surface of the series in relation to a standard index of refraction of 1.53 between 3.2 D and 6.7 D.

摘要： A blocking piece for vacuum blocking a lens blank is disclosed. The blocking piece includes a blank contacting element formed of a rigid fluid-permeable material having an upper surface for contacting the lens blank. The blocking piece further includes a support element having an upper part tightly enclosing the blank contacting element on a peripheral surface of the blank contacting element and a lower part adapted to engage with a clamping device for clamping the blocking piece. The lens blank is fixed to the upper surface of the blank contacting element by applying a vacuum within the blocking piece to provide suction through essentially the entire upper surface of the blank contacting element. The disclosure further relates to a method for blocking a lens blank and a use of an element formed of a rigid fluid-permeable material as a part of a blocking piece.

摘要： A tool for the polishing of an optical surface has a base which has an active surface facing the optical surface. An intermediate layer is arranged on the active surface of the base. A polishing agent carrier is arranged on the elastic intermediate layer. The elastic intermediate layer projects radially beyond the active surface of the base and the polishing agent carrier projects radially beyond the elastic intermediate layer.
