Abstract
In a fluorescence spectrophotometer comprising a light source, an excitation monochromator, a sample cell, an emission monochromator, a photodetector and a signal processing device, an excitation light polarizer and an emission light polarizer are disposed in the excitation light path and the emission light path, respectively, and the excitation and emission light wavelengths of the two monochromators are changed simultaneously in accordance with each of a plurality of wavelength conditions, and in each of the wavelength conditions, the direction of polarization of the emission light polarizer is changed between two orthogonal directions, in each of which the output of the detector is sampled by the signal processor, and the processed data is stored so as to be used for calculation of the degree of polarization of the polarized fluorescent light from the sample.
