Abstract
An illumination device includes: an objective; a first scanning device that moves a focusing position of light in an optical-axis direction of the objective; and a relay optical system that is configured to correct an aberration that is generated in the objective by the first scanning device moving the focusing position, the relay optical system being arranged on an optical path between the first scanning device and the objective.
