Abstract
Disclosed herein is a fluorescence measuring apparatus capable of determining whether accuracy of measuring fluorescence lifetime is deteriorated or not due to adjustment of the apparatus. The fluorescence measuring apparatus for measuring fluorescence emitted when an objects to be measured are irradiated with laser light includes: a laser light source that irradiates each of the objects to be measured with intensity-modulated laser light; a light-receiving unit that receives fluorescence emitted when each of the objects to be measured is irradiated with the laser light; a signal processing unit that determines a fluorescence lifetime using a signal of the fluorescence received by the light-receiving unit; and a determining unit that determines whether or not a fluorescence lifetime dispersion of the objects caused by amplification of the signal of the fluorescence performed by the light-receiving unit or by the signal processing unit is larger than a predetermined value.
