Abstract
A method of manufacturing an optical article, wherein an output light flux generating process of generating an output light flux by inputting a light from a light source to an output setting element having a repetition structure; a cured layer forming process of forming a cured layer at an irradiation area that is formed in correspondence with the output area by introducing the output light flux through a projection optical system into a container in which light-curable resin is contained and a stage is arranged and condensing the output light flux; and a stage moving process of moving the stage in a desired distance along the direction of the output flux propagating, are sequentially performed in this order and an irradiation variation process of varying the irradiation area in the cured layer generating process are further included, thereby the optical article is formed on a surface of the stage.
