Abstract

PURPOSE:To detect fluorescence surely by subtracting fluorescence intensity from the apparent reflected light intensity in the wavelength of lighting light of reflected light spectra and calculating a spectral reflected radiance factor and a spectral fluorescence radiance factor. CONSTITUTION:The device consits of a lighting spectroscope M1 and a reflection spectroscope M2. In the spectroscope M2, a multichannel photometric element D is disposed along the spectral image plane, and the operation of interpolating the fluorescence intensity at the wavelength of lighting light from the reflected light spectra of a sample Sm is accomplished at every wavelength in the wavelength scanning of the spectroscope M1. The interpolated fluorescence intensity is subtracted from the apparent reflected light intensity at the lighting light wavelength of the reflected light spectra in an arithmetic circuit. The fluorescence intensity is divided by the ratio of the wavelength width of the spectroscope M2 to the wave- length width of the spectroscope M1. An arithmetic circuit calculating a spectral reflection radiance factor and a spectral fluorescence radiance factor from these two is provided.
