Patent ID: 8913240

Claim:
A fluorescence spectrophotometer, comprising: a light source; a sample cell; an excitation-side light-dispersing system for dispersing a light from the light source and for casting a desired wavelength of light into the sample cell; an emission-side light-dispersing system for dispersing a light emitted from the sample cell, the emission-side light-dispersing system being located off an optical path of a transmitted light exiting from the sample cell after being cast from the excitation-side light-dispersing system into the sample cell; a photodetector capable of detecting, among the light from the emission-side light-dispersing system, an emission light having a same wavelength as the light cast from the excitation-side light-dispersing system into the sample cell; a controller for continuously varying a set wavelength of the excitation-side light-dispersing system and a set wavelength of the emission-side light-dispersing system over a predetermined wavelength range while keeping the two wavelengths equal to each other; and a spectrum data acquirer for obtaining spectrum data from detection results obtained with the photodetector for each of the set wavelengths of the excitation-side light-dispersing system and the emission-side light-dispersing system.
