PROBLEM TO BE SOLVED: To simultaneously perform a time-dissolved measurement and a spectral measurement in spectrometery. SOLUTION: Excitation light and probe light which contains a plurality of wavelengths are formed, the probe light and the excitation light are overlapped so as to be irradiated at a sample in such a way that the probe light has the optical delay time at least on a sample face, information on a reaction product due to the excitation light is read out in a shape of optical information by the irradiation of the probe light, the time base and the wavelength axis of the optical delay time are spectrally diffracted into two dimensions of the time base and the wavelength axis of the optical delay time so as to be spectrally diffracted in real time into the time width of the optical delay time, and the time-dissolved measurement and the spectral measurement are performed simultaneously.
