Optical part manufacturing method, mold manufacturing method, optical part manufacturing apparatus, and mold manufacturing apparatus

摘要

The present invention provides an optical part manufacturing method and an optical part manufacturing apparatus capable of manufacturing optical parts, whereby aligning an optical part with a bonded member and bonding the optical part and the bonded member can be accomplished successively, and a mold manufacturing method and a mold manufacturing apparatus capable of manufacturing a mold that is used to mold optical parts as above. A molding apparatus 10 performs a deformation step of bringing a light curing resin and a first transfer body 102 having a profile to form an optical element 404 and projections 406 in the light curing resin into contact with each other and deforming the light curing resin to copy the profile of the first transfer body 102, a hardening step of hardening the deformed light curing resin, a detaching step of detaching the light curing resin and the first transfer body 102 from each other, and repeats a transfer step of transferring the profile of the first transfer body 102 to the light curing resin a plurality of times to manufacture a lens array 402.

主权项

1. An optical part manufacturing method comprising:
a deformation step of bringing a molding material and a transfer body having a transfer element including an optical element forming part to form an optical element in the molding material and projection forming parts to form projections in positions apart from a position where the optical element is formed in the molding material during one said deformation step, the deformation step forming the projections extending from the optical part, which come in direct contact with a surface of a bonded part, the surface facing the optical element, the optical element forming part and the projection forming parts being arranged on a planar surface of the transfer element and spaced apart from each other on said surface of the transfer element and defining a profile of the transfer element, and the projection forming parts being generally circular recesses disposed at even intervals around the optical element forming part, and deforming the molding material to copy a counter profile of the profile of the transfer element; a hardening step of hardening at least a deformed area of the molding material; and a detaching step of detaching the molding material and the transfer body from each other, wherein a transfer step of transferring the profile of the transfer element to the molding material is repeated a plurality of times to manufacture an optical part.
