A compensating pad for applying to an ophthalmic lens blank to be blocked, or for interposing between an ophthalmic lens blank and a block piece. The compensating pad comprises a main body that is designed to be elastic having a maximum thickness corresponding to a maximum layer thickness difference of the ophthalmic lens blank, in order to locally compensate for the layer thickness difference of the blocked ophthalmic lens blank.

Compensating pad

A device for blocking workpieces has an aligning station that includes a workpiece support for aligning a workpiece. A blocking station comprises a block piece mount and serves to block the aligned workpiece by use of a block material on a block piece, which can be mounted in the block piece mount in a centered manner in relation to a substantially vertically extending blocker axis. A workpiece carriage carries a holding head for the workpiece and is suitably guided and driven to transport the workpiece from the aligning station to the blocking station to position the workpiece along the blocker axis in a defined manner relative to the block piece held in the block piece mount, and to hold the workpiece during blocking in the defined relative position to the block piece with a gap between workpiece and body piece.

Device for blocking workpieces, particularly spectacle lenses, for the processing and/or coating thereof

A blocking unit for a block piece for a spectacle lens comprising a block piece reception body with a reception surface adapted to receive a block piece with a spectacle lens to be blocked and a bottom surface opposite the working surface, and a plurality of light sources fixedly mounted to the block piece reception body. A process of curing a lens on a block piece. The process comprises the steps of defining, in a controller, a pattern of illumination, and sequentially turning on and off the light sources from a plurality of first light sources and optional second light sources based on the determined pattern, for curing a material between the lens and the block piece.
