Abstract
A fluorimeter comprises an excitation optical system projecting the excitation light having a selected wavelength for a sample to said sample, a sample cell for accommodating the sample; fluorescent light sensors for sensing the fluorescent light emitted from the sample; a transmission light sensor for sensing the light transmitted through the sample; and an arithmetic divider which divides the output of the fluorescent light sensor by the output of the transmission light sensor, and provides a signal representing the intensity of the fluorescent light which is corrected against the variation of the excitation light intensity.
