Being the preform item of the resin make optical component where the optical functional aspect which forms the production mannered null optical function

摘要

PROBLEM TO BE SOLVED: To provide a preform product of an optical element made of a resin constituted so as to make it possible not only to easily prevent air from remaining on an optically functional surface at the time of press molding of the optically functional surface but also to protect the optically functional surface of the optical element after molding, the optical element made of the resin and a method for manufacturing the same.;SOLUTION: A transfer part (11) is provided to at least one surface of the preform product (10) so as to become flush with the peripheral edge part (12) provided to the peripheral edge of the preform product or to be arranged inside the peripheral edge part (12) and an air escape groove (13) is provided between the transfer part (11) and the peripheral edge part (12).;COPYRIGHT: (C)2003,JPO
