Abstract: An illumination unit emits illumination light to a specimen. An image sensor includes multiple pixels arranged in a two-dimensional manner on a photoelectric surface. The image sensor captures an image of a magnitude distribution of an interference pattern formed due to the illumination light that has interacted with the specimen. A limiter limits at least one from among the spatial frequency of the interference pattern formed on the photoelectric surface and the incident angle of the light input to the photoelectric surface.
