摘要
A phase object visualization apparatus includes: an illumination optical system 11 that illuminates a phase object; an image formation optical system 12 that forms an image from light from sample S that corresponds to the phase object; and light blocking unit 10 for blocking light, the light blocking unit 10 being disposed between the sample S and an image plane formed by the image formation optical system 12, and including an aperture at a position decentered from the optical axis of the image formation optical system 12. The position of the aperture is such that an area occupied on the aperture by 0-order diffraction light from the sample S illuminated by the illumination optical system 11 becomes smaller than the total area of the aperture.
