摘要： An illumination apparatus includes a light guide fiber receiving illumination light, which is generated by first to third light sources, with first to third entrances and emitting at least part of the illumination light received by each entrance from a common exit. A second illumination relay optical system optically relays the illumination light from the second light source to form a first light beam having a first angle of incidence and sends the first light beam to the second entrance. First and third illumination relay optical systems optically relay the illumination light from the first and third light sources to form a second light beam having a second angle of incidence differing from the first angle of incidence and send the second light beam to the first and third entrances.

摘要： A method of adjusting optical imaging system is provided to finely adjust arrangement of optical elements with sensitivity. Illumination light with a predetermined wavelength band is irradiated to an adjustment mark including first marks disposed at a first pitch and second marks disposed at a second pitch different from the first pitch. An image is captured according to light, of diffracted light emitted from the adjustment mark, passing through an aperture stop and reaching an image surface of the optical imaging system. A positional deviation between the first and second marks is calculated with symmetric/asymmetric property of luminance information. Based on respective positional deviations calculated while the wavelength band of illumination light is changed, arrangement of optical elements between a pupil plane and an aperture stop surface of the optical imaging system is finely adjusted, to correct imaging positional deviation of a pupil image on the aperture stop surface.
