Document Type and Number:
WIPO Patent Application WO/2020/148860
Kind Code:
A1
Abstract:
This manufacturing method of an imaging device for an endoscope involves: a manufacturing step S10 for manufacturing an optical unit 10 which comprises multiple stacked optical elements 11-15, and an imaging element 40 which includes an imaging element 30 having a light receiving surface 30SA; a measurement step S20 for measuring the position of the image plane FP where a subject image, focused by the optical unit 10, is formed; an interval adjustment step S40 for adjusting the interval between the optical unit 10 and the imaging unit 40 so that the image plane FP, measured in the measurement step S20, is in the position of the light receiving surface 30SA; and a curing step S50 in which, by curing resin 50 arranged between the optical unit 10 and the imaging unit 40, fixes the optical unit 10 and the imaging unit 40 in the state with the interval having been adjusted in the interval adjustment step S40.
