    摘要： An apparatus for blocking an ophthalmic lens blank for working the lens includes an alignment station for supporting and aligning the lens blank relative to a target image and a transport means for moving the lens from the alignment station to a blocking station while maintaining lens orientation. The blocking station includes a support for a lens block, support for the lens, and a mechanism for injecting heated liquid bonding material between lens and block which solidifies on cooling to join the lens and block.

    摘要： In an apparatus for performing work operations on a surface of one or more lenses, a frame and a mounting bracket adapted to releasably support at least one lens blank are provided. At least three pairs of articulated supports are also included with a first end of each of the supports being bendably coupled at a first end to a mounting bracket adjacent to the other articulated support in the pair. The articulated supports are each coupled at a second end to a point on the frame with the supports in each of the pairs diverging away from each other between the mounting block and the frame. A drive is associated with each of the articulated supports and moves each support, and thereby the mounting, individually between a raised and a lowered position in response to commands issued from a controller having data corresponding to a particular lens prescription stored therein. A machining surface is also provided and during operation, as the mounting bracket moves in response to the action of the articulated supports, the lens is engaged with and moves over the machining surface thereby performing a work operation on the lens.

    摘要： In a conformable lap and related method for finishing ophthalmic lens surfaces, a rigid base surface of the lap defines a nominal ophthalmic lens curvature corresponding to a predetermined range of curvatures. A work surface of the lap is defined by a thin, hard, polymeric material extending adjacent to the base surface for contacting a selected ophthalmic lens surface and conforming to the curvature of the selected surface. A selectively conformable substance consisting of a mixture of thermoplastic and metallic particles forms a layer extending between the rigid base surface and the work surface, and is selectively changeable between solid and non-solid forms. In its non-solid form the conformable substance permits movement of the work surface relative to the base surface to conform to the curvatures of any one of a plurality of ophthalmic lens curvatures within the predetermined range of curvatures, and in its solid form the substance fixes the work surface in a position conforming to the curvature of a selected lens surface and retains the conforming position during finishing of the lens surface.
