Abstract: An observation device including: a stage having a transparent pedestal surface; an illumination system under the pedestal surface, the illumination system emitting illumination light toward the pedestal surface; and an object system under the pedestal surface for capturing transmission light generated from the illumination light, reflected off a reflection surface and transmitted through a sample. Wherein a first light path in the illumination system is different from a second light path in the object system, in a first pupil surface of the illumination system, the illumination system generates the illumination light by restricting light in a first transparent region, in a second pupil surface of the object system, the object system restricts the transmission light in a second transparent region, and the second transparent region has first and second subregions with different transmittance, the second subregion located between the first subregion and an edge of the second transparent region.

Abstract: It is possible to observe imaging subjects, such as cells or the like, without causing an increase in the apparatus size. Provided is an observation apparatus including: a flat-plate-like stage formed of an optically transparent material on which a container accommodating a sample is placed; a deflecting member that is disposed below the stage and that deflects light coming from the sample on the stage into a substantially horizontal direction; an objective lens that collects the light deflected by the deflecting member; and an image-acquisition device that captures the light collected by the objective lens.
