Abstract
Disclosed herein is a fluorescence measurement device for a living body configured to be able to reduce wavelength components that will become leak light and to easily switch a wavelength and an irradiation direction. The fluorescence measurement device for a living body comprises: a sample holder on which a living body sample is to be placed; an exciting light-irradiating device having a plurality of exciting light sources arranged at mutually different positions, each of which is composed of a laser diode or a light-emitting diode and is provided with a filter having an optical property to eliminate, from a spectrum of the exciting light source, disturbing wavelength components overlapping with wavelength components of fluorescence to be detected; an electrical switch for switching lighting of the exciting light sources; a detector for picking up an image produced by fluorescence emitted from the sample placed on the sample holder; and an image display device for displaying the image picked up by the detector.
