METHOD OF PRODUCING GLASS OPTICAL ELEMENTS

摘要

PROBLEM TO BE SOLVED: To produce a large number of glass optical elements such as microprisms at a time and to improve the productivity. SOLUTION: The method of producing glass optical elements includes step 201 to press-form a glass material with molding dies including at least an upper die 32 and a lower die 31 to obtain a glass body 40 having first and second faces of a desired form and surface accuracy formed by the upper and lower dies and having a plurality of recesses and projections on at least the first face 40b, and step 203 to cut and separate the glass body into a plurality of products each containing at least one of the recesses and projections of a specified form on the first face 40b and containing at least a part of the second face so as to obtain a plurality of glass optical elements 10.
