METHOD FOR PRODUCING OPTICAL ELEMENT MOLDING DIE, METHOD FOR PROCESSING OPTICAL ELEMENT MOLDING DIE, AND OPTICAL ELEMENT MOLDING DIE PROCESSED THEREBY |
摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide an optical element molding die capable of stably repeating molding without causing adhesion of fused glass, to provide a method for producing the same, and to provide a method for processing the same. <P>SOLUTION: A method for producing an optical element molding die 1 for molding an optical element by press-molding a glass material M is provided. This method comprises the step of forming a surface layer 3 coming into contact with the glass material M in press molding on a die base material 2 comprising cemented carbide or silicon carbide and the heating step of heating the surface layer 3 to oxidize its superficial part into thermally oxidized layer 5. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
