Patent ID: 7046461

Claim:
A manufacturing apparatus for manufacturing an optical device including: a plurality of optical components arranged on an optical path of a light beam irradiated by a light source; and an optical component casing in which an illumination optical axis of the light beam is set and the optical components are housed and arranged at predetermined positions on the illumination optical axis, the optical component casing having at least one opening penetrating toward the inside thereof, the manufacturing apparatus comprising: an optical component positioning jig arranged at designed predetermined positions of the plurality of optical components and having a plurality of holders for holding the plurality of optical components, the optical component positioning jig being capable of adjusting the position of the optical component; an optical component casing holder for holding the optical component casing so that a part of the optical component positioning jig can be inserted into the opening; a light beam irradiator for conducting a light beam to the optical device; an optical image detecting device for detecting an optical image irradiated by the light beam irradiator and passed through the plurality of optical components; a jig driver that drives the optical component positioning jig; and a controlling unit for controlling the jig driver, the controlling unit including: an image capture that captures an image detected by the optical image detecting device and converts the image into an image signal; a luminance acquiring unit that acquires a luminance value of the image based on the image signal output from the image capture; and an arithmetic unit that computes a position adjustment amount of the optical component based on the luminance value acquired by the luminance acquiring unit.
