<p>A spectral measurement device includes an optical band-pass filter section having a spectral band of first to n-th wavelengths (n is an integer of 2 or more), a light receiving section, a correction operation section, and a signal processing section. When an m-th wavelength band (1≰m≰n) is an interest wavelength band, and a k-th wavelength band (k≠m and 1≰k≰n) other than the m-th wavelength band is a non-interest wavelength band, the optical band-pass filter section functions as a m-th band-pass filter corresponding to the m-th wavelength band and a k-th band-pass filter corresponding to the k-th wavelength band.</p> |
