PROBLEM TO BE SOLVED: To improve measurement accuracy of a spectrometer without using, for example, an expensive optical bandpass filter.SOLUTION: The spectrometer comprises: an optical bandpass filter part 300 having from a first wavelength range to an n-th wavelength range (n is an integer of 2 or more) being predetermined wavelength widths as spectral bands; a light receiving part 400 for receiving light from the optical bandpass filter part; a correction operating part 500 for performing a correction operation which corrects light receiving signals obtained based on output signals from the light receiving part; and a signal processing part 600 for performing a predetermined signal processing based on the light receiving signals after the correction by the correction operating part 500. The correction operating part 500 corrects the light receiving signals based on a change of the spectral distribution of the light receiving signals. |
