Method for making holder/optical-element assembly

摘要

A method for making a holder/optical-element assembly (1) includes the steps of positioning a cylindrical holder material (10a) in a press-molding die (A, B, C), the holder material having a void part (14) in the inner circumferential surface, positioning an optical-element material (20a) inside the holder material, heating the holder material and the optical-element material to their own softening temperatures, press-molding the holder material and the optical-element material, which are heated, to form a cylindrical holder (10) and an optical element (20), respectively, thereby fixing the optical element to the inside of the holder, allowing a part of the optical element to project outwardly from the outer edge by pressure created in press-molding, and retaining the projected portion in the void part of the holder.
