FORMING MOLD SET FOR FORMING OPTICAL ELEMENT, PRODUCTION DEVICE PROVIDED THEREWITH, AND METHOD FOR PRODUCING OPTICAL ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a forming mold set capable of easily producing an optical element in which the clouding of the surface and the sticking of volatile matter are suppressed. SOLUTION: In the forming mold set 2, a gas feed path 24 for feeding an atmospheric gas to a cavity C is formed. An atmospheric gas fed to the cavity C is exhausted from a gap between an upper mold 22 and/or a lower mold 21 and a body mold 23. COPYRIGHT: (C)2007,JPO&INPIT
