Problems solved by technology

Therefore, the molten state and the solidified state have a great influence on the state of the first optical functional surface, and as a result, have a great influence on the optical performance of the composite optical element.
For example, when the first optical functional surface is deformed due to melting or joint unevenness occurs, the optical performance is degraded

Abstract

This device (60) for producing a composite optical element (10) comprises: a first cavity section (81) that molds, with a first molding material (20a) in a primary molding step, a first optical element section (20) having a first optical function surface (29) in a portion thereof; and a second cavity section (101) that molds, with a second molding material (40a) in a secondary molding step, a second optical element section (40) provided to the first optical element section (20) so as to cover the first optical function surface (29), the second cavity section molding a composite optical element (10) by integrating the second optical element section (40) with the first optical element section (20). The production device (60) has a second discharge opening section (103a) in which the discharge direction of the second molding material (40a) from a second supply path section (103) to the second cavity section (101) is along the first optical function surface (29).

Description

technical field [0001] The present invention relates to a manufacturing device of a compound optical element and a manufacturing method of the compound optical element. Background technique [0002] For example, Patent Document 1 discloses a molding method and a molding die for molding a composite optical element by two-color molding. This composite optical element is molded by joining two optical element parts to each other. [0003] In the composite optical element described above, the first optical element part is molded with a first meltable molding material in primary molding, and the second optical element part is molded with a second meltable molding material in secondary molding. The first optical element part has a first optical function surface arranged on the outer peripheral surface of the first optical element part. In secondary molding, the second optical element portion is integrated with the first optical element portion by covering and joining the first op...
