摘要：A sample S is irradiated with pulsed pumping light supplied from a pumpinglight source , fluorescence generated by the sample S is detected by a photodetector by

way of a condensing optical system and a spectroscope and the fluorescence timewaveform is subjected to a data analysis in a data processing unit in a controller so as tocompute waveform data and physical quantities such as fluorescence lifetime. Here, thepumping light time waveform is fixedly arranged with respect to a time axis used for thedata analysis, a plurality of fitting calculations are carried out while moving thefluorescence time waveform and fitting range from an initial position earlier than apumping light peak to a later end position, and optimal measurement waveform data isselected according to a predetermined selection criterion. This realizes fluorescencemeasuring method and apparatus which can compute waveform data and the likeaccurately and efficiently regardless of fluctuations in the fluorescence time waveform,and a sample evaluating apparatus using the same.
