    摘要: A method for making optical preforms of optical elements without residual stress or distortion is provided. In this method, an optical material is supplied between upper and lower molds. The upper mold has a plurality of recesses arranged in a predetermined pitch, and each recess corresponds to a first surface shape of the optical element. The lower mold has a plurality of recesses facing the recesses of the upper mold and each recess of the lower mold corresponds to a second surface shape of the optical element. The supplied optical material is pressed between the upper and lower molds to be a set of optical preforms. The set of optical preforms is processed by die punching or tool cutting to separate each optical preform from the set of optical preforms. Each optical preform is used for producing an optical element by further pressing. Alternatively, optical element can be formed directly by the press molding process.

    摘要: A die for press-molding an optical element with high precision comprises a base material made of a material excellent in heat resistance, heat shock resistance and mechanical strength at high temperature, an intermediate layer formed on the base material and made of a thin film excellent in grinding machinability and cutting machinability, and a surface protective layer formed on the intermediate layer and made of a metal thin film excellent in heat resistance and mechanical strength at high temperature and less reactive to a material of the optical element. Additional thin film may be inserted between the base material and the intermediate layer so as to enhance the adhesion strength between the base material and the intermediate layer. In place of the additional thin film to be inserted, a peripheral flange part of the intermediate layer is removed and thus on the removed peripheral part, the surface protective layer is directly adhered to the base material.

    摘要: A method of manufacturing optical elements which is capable of obtaining optical elements at high accuracy by molding through employment of an optical element molding glass material preliminarily processed to prevent such defects as crack formation or chipping at the corner portions of the molding material which contact dies when the material is charged into the mold. An optical element molding glass material to be employed for the above method is formed with curvatures at boundary portions i.e. corner portions where its cylindrical portion contacts at right angles with its end flat portions by applying chemical etching, heat of a carbon dioxide gas laser or radiation heat to such corner portions. Meanwhile, in the manufacturing process of the optical element in which upper and lower dies and the preliminarily processed molding material are subjected to molding through heating and pressurization in a contacted state at all times, the molding pressure is arranged to be reduced at least one or reduced to zero to provide the optical element at high accuracy.
