COMPOUND OPTICAL ELEMENT AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To raise coincidence accuracy of optical axes of two optical parts in a compound optical element. SOLUTION: A 1st optical part 10 is pressed by a bell clamp shaft 40 and an outer peripheral part of the 1st optical part 10 is brought into contact with a contact part R of about R shape formed at a peripheral part of a forming surface 37a of a forming die 37 to perform center regulation by bell clamp action. A thermosetting resin 38 and the 1st optical part 10 are pressed by the bell clamp shaft 40 and the forming die 37 while performing center regulation by the bell clamp action to form the compound optical element 1.
