MATRIX FOR DIE, MOLDING DIE USING THE SAME, METHOD OF PRODUCING OPTICAL ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a molding die for press-molding a glass material, to provide a matrix for a die for producing the same, and to provide a method of producing an optical element using the molding die. SOLUTION: An electroforming die 12 for forming a lattice pattern composed of nickel or nickel-phosphor is formed with a matrix 10 formed of a glass material. For example, a glass sheet 14 formed of phosphate glass is pressurized/pressed under 300 kg/cm at 310°C in a vacuum to form a diffraction grating 2. COPYRIGHT: (C)2005,JPO&NCIPI
