Title:
METHOD FOR PRODUCING OPTICAL ELEMENT, AND OPTICAL ELEMENT MOLDING DIE
Document Type and Number:
WIPO Patent Application WO/2011/105186
Kind Code:
A1
Abstract:
In order to provide an optical element manufacturing method capable of molding optical elements with a high degree of precision, an optical element manufacturing method for producing optical elements that have opposing optical surfaces by means of a pair of molding dies that have molding surfaces for molding the optical elements is configured so that each molding die is provided with a molding surface for molding a first optical element and a molding surface for molding a second optical element, which is distinct from the molding surface for molding the first optical element and is used to adjust the relative positions of the pair of molding dies, and so that each molding die is used to perform a molding step in which the second optical element is molded, a measurement step in which the relative displacement of the opposing optical surfaces is determined on the basis of the transmitted wavefront aberration of the second optical element molded in the molding step, a relative position adjustment step in which the relative position of the pair of molding dies is adjusted on the basis of the relative displacement determined by the measurement step, and a second molding step in which the first optical element is molded using the molding die, the relative position of which has been adjusted by the relative position adjustment step.
