Abstract

A fluorescence spectrophotometer comprising a light source, an excitation side monochromator which makes light from the light source be subjected to spectroscopic analysis for illuminating as actinic light a sample, a fluoroscence side monochromator which makes fluorescence light from the sample be subjected to spectroscopic analysis, a detector which detects light from the fluorescence side monochromator, and a scanning means which adjusts both the monochromators to the wavelengths of the actinic light and the fluorescence light to be scanned. These monochromators are arranged in such a way that one of them is automatically set to the location of the peak wavelength value which is detected by itself through a simple and automatic wavelength scanning operation and then the other is wavelength-scanned for excitation spectrum or fluorescence spectrum measurement.
