Optical-device forming method and apparatus

摘要

A method and apparatus for forming an optical device of a desired shape presses a heat-softened optical material using a set of molds. The optical material is aligned with respect to the molds by two or more aligning members which move around the center of the mold relative to each other. The optical material may also be aligned by inserting a pin into an aligning hole which is fixed to the mold body and has been aligned with respect to the molds.
