Abstract: An image acquisition device includes an optical system, an illumination angle adjustment mechanism, and a stage. The optical system has a lens and a light source disposed in the focal plane of the lens, and generates a collimated illumination light. The illumination angle adjustment mechanism is configured so as to be able to change the irradiation direction of the illumination light with respect to an object. A module is detachably loaded on a stage. The module includes the object and an image sensor which are integrated such that the illumination light transmitted through the object is incident on the image sensor. The stage has a circuit for receiving an output of the image sensor in a state where the module is loaded on the stage.
