摘要： PURPOSE:To enable optical effective diameter of a desired lens, reduce heat capacity of a mold and enhance forming efficiency by providing a nonspherical machined diameter of a nonspherical lens forming mold with a difference between the shrinkage length of the lens and a shrinkage length of the forming mold added to the optical effective diameter of the lens. CONSTITUTION:In a forming mold forming a nonspherical lens having a top force 1 and a bottom force 2 in which the optical functional surface of at least one thereof has a nonspherical shape and a drum mold 5 for aligning the axial center of the forming mold and sliding the mold in the vertical directions, the machined diameter of a nonspherical surface of the forming mold is regulated to a difference between the shrinkage length of the lens from the heating temperature to ordinary temperature [the optical effective diameter (E) of the lens at a high temperature - the optical effective diameter (C) of the metallic mold at ordinary temperature] and the shrinkage length of the forming mold from the heating temperature to ordinary temperature [the optical effective diameter (D) of the metallic mold at the high temperature - the optical effective diameter (C) of the metallic mold at ordinary temperature] added to the optical effective diameter (C) of the lens.

摘要： PURPOSE:To obtain a high accurate plastic lens, by previously obtaining through experiment a change by aging, internal distortion and a machining distortion, which are generated in accordance with an external diameter of the lens, its thickness and its shape or the like, and machining a surface shape of the lens. CONSTITUTION:A lens surface is machined by experimentally obtaining a change quantity, due to machining distortion of a lens and its internal stress or the like, to be incorporated in a design value shape. The first surface is cut in a shape 7 estimating a change quantity A'' for a desired shape 6. The second surface is cut in a shape 9 anticipating a change quantity B' for a desired shape 8. Thereafter, the machining method, leaving the lens naturally as it is for several days or applying heat treatment, obtains the lens in the desired shape 6, 8.

摘要： PURPOSE:To permit the polishing with high precision and high efficiency by forming a composite polisher for polishing the surface of a shaping metal mold for a lens, etc., which are machine-worked with high precision, from the composite constitution through the mixed solidification of the joint material consisting of high polymeric material and the metal material. CONSTITUTION:As the composite polisher material, is prepared the fibrous metal 2 which is made of tin and adjusted to the dimensions of thickness of 0.1mm, width of 1.0mm, length of 10 mm or so and applied with a primer after being cleaned and degreased. The fibrous metal 2 in 10wt.% and the high polymeric material 1 such as shaping silicone rubber in 90wt.% are uses. After these materials are mixed, the material is poured into a polisher shaping mold which is made of resin and has the shape which is most advantangeous for polishing of a workpiece 4, preferably so that the fibrous metal 2 is dispersed only on the surface layer part of the composite polisher, and the desired composite polisher is manufactured by solidifying the high polymeric material 1. The workpiece is polished by supplying the slurry 5 containing fine abrasive grains.

摘要： PURPOSE:To provide the subject mold enabling optical elements to be furnished at low cost by making conventional marking operations needless. CONSTITUTION:The optically non-functional surface 13 situated on the molding surfaces of a pair of top and bottom molds serving as a mold 11 for optical elements is provided with small recesses 16, 17; the point group at each of the recesses 16, 17 is designed to represent letters, figures or signs and clarify the correlation with optical element. Besides, in cooling operation after molding, shrinkage difference is developed through the parts as nuclei filled in the point group to develop moderate non-point aberration while maintaining the performance of the entire optical element, thus making conventional marking operations needless.

CONSTITUTION:A top force 1 and a bottom force 2 in which the optical functional surface of at least one thereof has a nonspherical shape and a drum mold 5 for aligning the axial center of the forming mold and sliding the mold in the vertical directions are used to form a nonspherical lens. In this case, the machined diameter of a nonspherical surface of the forming mold is regulated to a difference between the shrinkage length of the lens from the heating temperature to ordinary temperature [the optical effective diameter (E) of the lens at a high temperature - the optical effective diameter (C) of the metallic mold at ordinary temperature] and the shrinkage length of the forming mold from the heating temperature to ordinary temperature [the optical effective diameter (D) of the metallic mold at the high temperature - the optical effective diameter (C) of the metallic mold at ordinary temperature] added to the optical effective diameter (C) of the lens.
