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.

摘要： 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.

摘要： A system for monitoring the position of a blocking device on an ophthalmic lens (20) having at least one marking comprises: a mechanical structure adapted to cooperate with the blocking device; an image sensor (4) observing the ophthalmic lens (20); a control unit (10) connected to the image sensor (4) and configured to produce an image having a point of reference with a determined position with respect to the mechanical structure and at least part of the ophthalmic lens (20) including said marking; and a user interface (12) adapted to display a blocking device positional compensation proposal for an automatic positional compensation or for a manual positional compensation based on the comparison to a predetermined threshold of a distance between the point of reference and the marking on the image. A corresponding method and a method for edging an ophthalmic lens are also proposed.
