Abstract:
1. A fluorescence detection device that irradiates a sample holding carrier holding a fluorescently-labeled sample with irradiation light and detects fluorescence yielded from the sample irradiated with the irradiation light, the fluorescence detection device comprising: a light source that emits the irradiation light; an objective lens that converge the irradiation light at the sample on the sample holding carrier; an astigmatism element for introducing astigmatism to fluorescence having entered the objective lens from the sample holding carrier and having passed through the objective lens; a spectral element for separating the fluorescence into a plurality of light rays; and a fluorescence detector for receiving the light ray separated by the spectral element, wherein the spectral element disperses the fluorescence on a light receiving surface of the fluorescence detector so that fluorescence generated from the sample position is separated from fluorescence generated from a specific depth position other than the sample position, and the fluorescence detector has a light-receiving section in a region in which the fluorescence generated from the sample position is irradiated and the fluorescence generated from the specific depth region other than the sample position is not irradiated.
