    Abstract: An imaging apparatus (1) for imaging an imaging object carried together with liquid (M) in a sample container (W) with a bottom surface having optical transparency comprises: a holder (12) for holding the sample container; an imaging optical system (131, 132, 133, 135) having an object-side hypercentric property; a two-dimensional imaging element (136) for imaging an image of the imaging object focused by the imaging optical system; an illuminator (10) for illuminating the imaging object from a side opposite to the imaging optical system across the sample container held by the holder; a mover (15) for relatively integrally moving the imaging optical system, the two-dimensional imaging element and the illuminator with respect to the imaging object in a direction orthogonal to an optical axis of the imaging optical system; and a controller (14), wherein: the illuminator includes a plurality of illumination optical systems (100, 110) that have mutually different exit pupil positions and coaxially emit lights toward the imaging object; the controller is configured to cause one of the plurality of illumination optical systems to emit light and to cause the two-dimensional imaging element to image the imaging object when a relative position of the imaging optical system with respect to the imaging object reaches any one of a plurality of imaging positions determined in advance while causing the mover to relatively move the imaging optical system, the two-dimensional imaging element and the illuminator with respect to the imaging object, and to switch the illumination optical system for emitting the light according to the imaging position.
