<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing optical elements, by which optical elements each having a high precision optical surface can be manufactured at high manufacturing efficiency by uniformizing the cooling rates at the center part and the end part of molten glass. <P>SOLUTION: The method for manufacturing the optical elements includes: a heating process for heating a forming mold to a prescribed temperature; a molten glass supply process for supplying molten glass to the forming mold; a cooling process for cooling the molten glass by bringing a cooling member into contact with the upper surface of the supplied molten glass; and a forming process for press-forming the molten glass. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
