An optical system focuses a plurality of light beams emitted from the point light sources into a single light beam and irradiates a target object to be irradiated with the single light beam. The single light beam is obtained with a desired light intensity profile according to a combination of positions where the point light sources are arranged and intensity distributions of the light beams emitted from the point light sources.
