Abstract
A photodetection device has an optical module () that includes a light source (), an excitation optical system, and a detection optical system and that two-dimensionally and relatively scans a transparent stage () in a first sampling direction and a second sampling direction intersecting the first sampling direction. A scan length in the first sampling direction is longer than a scan length in the second sampling direction. A data sampling unit in the detection optical system performs sampling for a distance of a second sampling interval during scanning in the second sampling direction, and performs sampling for a distance of a first sampling interval shorter than the distance of the second sampling interval during scanning in the first sampling direction. An aperture () of the excitation optical system sets a size in the first sampling direction of a spot shape of excitation light from the light source () to be smaller than a size in the second sampling direction.
