Abstract
A method of producing a die for forming an optical element including; a positioning step to fix temporarily under the state wherein a plurality of members at least one of which has a die transfer surface are positioned with their connection surfaces being put to face each other, and an electroforming connection step to connect both members by forming an electroforming mold on a circumference of the connection surface under the state where the plural members are positioned.
Claims18
A method of producing a die for forming an optical element, comprising:
- forming an electrodeposited material on a base having a die transfer surface to form a die material, on which the die transfer surface has been transferred from the base, from the electrodeposited material;
- forming a connection portion on the die material to be connected with a connection portion provided on a supporting member;
- fixing temporarily the connection portion of the die material on the connection portion of the supporting member, while positioning the connection portions so as to face each other;
- and
- connecting the die material with the supporting member by forming an electrodeposited material on circumferences of the connection portions while positioning the die material and the supporting member.
