    摘要: A method for press molding preforms to obtain optical articles in which each preform is prepared beforehand to have a diameter larger than that of an optically functional area of the optical article and edges of the preform to be press mold contact with molding surfaces of a pair of molds outside an area of each molding surface corresponding to the optically functional area of the optical article, thereby elongating the lifetime of molds.

    摘要: A fusion welding method includes the steps of: generating a hybrid laser beam obtained by mixing a low-intensity laser beam with a first high-intensity laser beam and a second high-intensity laser beam; moving the hybrid laser beam along a gap between a first member and a second member; and melting the first member and the second member in the periphery of the gap with the hybrid laser beam, and filling the gap with the melt of the first member and the melt of the second member to weld the first member and the second member, wherein the first high-intensity laser beam is applied to the area of the first member to which the low-intensity laser beam is applied, and the second high-intensity laser beam is applied to the area of the second member to which the low-intensity laser beam is applied.

    摘要: A method is provided for manufacturing a high-precision mold whereby a feature matching a desired feature design is carved into a hard mold material (41) using, for example, a diamond grinding wheel and/or a diamond turning point. Inherent imprecision and errors (49) introduced by the use of the grinding wheel/turning point are measured to determine deviations from the desired feature design. An ultrafast shortpulse laser is then activated to desirably ablate the deviations, thereby correcting the errors and conforming the feature to the desired shape. Furthermore, a thin film (1602) may be formed over the feature either prior to or after the laser ablation process, where the error measurement and laser ablation processes detects and ablates errors on the surface of the thin film, respectively. Additionally, the laser ablation process may be applied directly to, for example, an optical lens (1400) formed from an imprecise mold to remove any errors and imperfections thereon.
