Abstract: A laser engraving device is adapted to process a plurality of lens blanks in a single processing run. The lens blanks are cut or edged serially where the laser cutter path for each blank is calculated by software which interprets lens blank optical parameters, prescription parameters and frame trace parameters, all of which can vary for each blank being edged. Minor adjustment of the angle of incidence between the laser cutter (20) and the target blank (23) is accomplished by a tiltable blank holder (24). More aesthetically appealing “rimless” lens are achieved by cutting the lens to have a frame-shaped edge from a single monolithic piece of blank material. Such shaping of the edge portion provides more ornamentation options on “rimless” eyeglasses.

Abstract: A laser cutting tool whose position, aiming direction and cutting duration are controlled by a programmable microprocessor, is housed in a cabinet above a platen equipped with a number of component-holding stations. Each of the stations has a plurality of vises sized to grasp an eyeglass component including lenses or lens blanks, a eyeglass frame, temple pieces, a nose bridge, a carrying case or a lens cleaning swatches. Program data sets specify the edging out of blanks of a particular optical property, and the engraving of the lens and other components with decorative patterns. A cylindrical cutting wheel mounted on a position-controlled carriage has a circular groove is also programmed to bevel the edges of the lenses.
