摘要： A method for determining a contour of a frame groove in a rim of a spectacle frame includes illuminating the rim, capturing a plurality of images of the illuminated rim from different predetermined perspectives, evaluating the captured images, and determining a spatial curve of the frame groove based on the evaluated images. The rim is illuminated along the entire circumference of the rim by directed illumination. Moreover, the evaluation of the captured images includes assigning each portion contained in the captured images to a respective surface element of the frame groove on the basis of at least one of the following properties: shadowing of the respective portion, brightness of the respective portion and phase angle of the illumination of the respective portion. Moreover, an apparatus, a computer program, a method for grinding a spectacle lens, and a computer-implemented method for determining a geometry of a spectacle lens are disclosed.

摘要： Disclosed is a lamination machine including: a film support for receiving a functional film to be laminated; an article support configured to receive and position the optical article in a predetermined orientation; and an actuating member configured to move the film support and the article support toward each other for laminating at a predetermined pressure the functional film received in the film support onto the optical article received within the article support. The article support is a blocker support configured to receive a surfacing blocker onto which the optical article is to be disposed for lamination, the article support being further configured to transmit laminating forces induced by the predetermined pressure to the lamination machine during a lamination operation.

摘要： A method for polishing a workpiece in the production of an optical element, in particular for microlithography, wherein a relative movement takes place between a polishing tool (300) and a workpiece surface (110, 120, 210) being machined. A polishing tool surface (215, 315) of the polishing tool (300) is formed by a viscoelastic polishing medium (303), wherein the polishing tool surface has an average diameter which is less than 50% of the average diameter of the workpiece surface being machined. The polishing tool surface during polishing is guided by an overrun distance beyond at least one edge (110a, 110b, 120a, 120b, 210a, 210b) delimiting the workpiece surface being machined, wherein the average diameter of the polishing tool surface is at least twice the overrun distance.
