Abstract
A fluorescence light detection device includes an excitation light fiber having an excitation light emitting end configured to emit excitation light; a fluorescence light fiber having a fluorescence light incident end on which fluorescence light is incident; an objective lens arranged between where the excitation light emitting end and the fluorescence light incident end are located, and a sample; and a reflective member arranged between where the excitation light emitting end and the fluorescence light incident end are located, and the objective lens, and having two reflective surfaces facing in opposite directions. The two reflective surfaces of the reflective member are positioned between an optical axis of the excitation light fiber and an optical axis of the fluorescence light fiber.
