Methods for edging optical articles comprising two main faces, at least one of which being coated with an outermost layer comprising fixing the optical article to a chuck with a holding pad that adheres to both the optical article and the chuck, wherein the surface of the holding pad contacting the optical comprises an adhesive material; and edging the optical article with an edging device; wherein prior to fixing the optical article to the chuck, at least one temporary layer of an organic material is formed onto said outermost layer of the optical article, the organic material of the temporary layer comprising at least one organic compound having a fluorinated functional moiety and at least one linking functional moiety capable of establishing at least one intermolecular bond or interaction with the adhesive material of the holding pad. Optical articles obtained via these methods.

In a method of preparing a lens blank for a surfacing operation, the lens blank is fastened to a support with a base and a support material via which the lens blank is fastened. The support material has a circular periphery. The surfacing transforms the lens blank into a surfaced lens. The method includes: determining the surfaced lens shape based on input data; based on the surfaced lens shape, determining a maximum diameter of the support material shape based on a predetermined maximum thickness defining the maximum thickness of the support material allowed to be cut into during the surfacing of the lens blank; choosing a diameter for the support material shape ≤the maximum diameter for further fastening the lens blank to the support by forming the support material so the support material shape has a diameter corresponding to the chosen diameter.

A polishing device for optical elements includes: a tool shank (1), and a polishing disc base; wherein the tool shank (1) is connected to the polishing disc base and is mounted on a tool shaft of a numerical-controlled processing device; wherein a polishing film (3) is stuck on the polishing disc base; the polishing disc base is a profiling polishing disc base (7), a cylinder polishing disc base (2), a profiling polishing disc base (12) or a spherical polishing disc base (8); wherein the tool shank (1) is independent and universal, thereby reducing the processing cost of the polishing device. A polishing method for optical elements is based on the shapes mentioned above of the polishing disc base, including steps of: fixing a polishing disc connecting rod (11); sticking a polishing film (3); trimming the polishing film (3); and polishing an unprocessed work piece (6).

A process for machining a lens includes the steps of holding a semi-finished product through a suction holding force which is active during an entire surface machining cycle of the semi-finished product; carrying out the surface machining cycle on a surface to be machined of the semi-finished product; and activating a pressure holding force depending on the level of the mechanical stresses exerted on the semi-finished product during the surface machining cycle on said surface.

Disclosed is a machine for acquiring images (1) including: a support (10) for optical lens, on one side of the support, a light source (20), on the other side of the support, an image sensor (30) suitable for capturing at least two images of the optical lens illuminated by the light source, viewed from two different angles.

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.
