Title:
METHOD FOR MANUFACTURING OPTICAL UNIT, OPTICAL UNIT, AND ENDOSCOPE
Document Type and Number:
WIPO Patent Application WO/2019/138463
Kind Code:
A1
Abstract:
This method for manufacturing an optical unit 1 is provided with: a step for preparing a plurality of element wafers 11W to 14W; a step for stacking the plurality of element wafers 11W to 14W to prepare a joint wafer 10W; a step for cutting the joint wafer 10W to prepare a laminate lens 10 in which a plurality of optical elements 11 to 14 that include a first optical element 11 having a first primary surface 11SA, are laminated; a step for preparing a lens frame 40 having a through-hole H40; and an assembly step for inserting the laminate lens 10 into the through-hole H40. The first element wafer 11W including the first optical element 11 prepared in the element wafer step is prepared through a molding method, a stepped part S10 is present around the first primary surface 11SA of the first optical element 11, and a front opening 40SA of the lens frame 40 is fitted to the stepped part S10 in the assembly step.
