Abstract: 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.

Abstract: Disclosed is an apparatus and method for processing eyeglass lens which determines the completion of the eyeglass lens processing by using a hall sensor. The eyeglass lens processing apparatus comprises: a grinding wheel mounted frame (22) mounted with a grinding wheel (20) for grinding a lens, and whose position is changed according to a predetermined grinding depth of the lens; a carriage (12) for moving the lens to contact with the grinding wheel (20), and which contacts with the grinding wheel mounted frame (22) when the lens which contacts with the grinding wheel (20) is grinded to the predetermined grinding depth; and a hall sensor detector (30) for detecting a contact of the grinding wheel mounted frame (22) and the carriage (12), wherein the hall sensor detector (30) includes a magnet (32) and a hall sensor (34) for detecting an intensity of a magnetic field generated by the magnet (32), the magnet (32) is equipped on either one of the carriage (12) and the grinding wheel mounted frame (22), and the hall sensor (34) is equipped on the other one of the carriage (12) and the grinding wheel mounted frame (22), in case an output signal of the hall sensor (34) is “A” when the grinding wheel mounted frame (22) and the carriage (12) are in contacts with each other, if the output signal of the hall sensor (34) is smaller or larger than “A” by a tolerance, it is determined that the grinding wheel mounted frame (22) and the carriage (12) are in a separated state.

Abstract: 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.
