Abstract
A spectral measurement device to detect measurement light including light emitted from a measurement object and to measure spectral characteristic of the light, including: a spectral optical system to disperse the measurement light; a detection unit to detect intensity of light dispersed by the spectral optical system; a spectral characteristic acquisition unit to acquire a measurement light spectral characteristic indicating a relationship between a light intensity and a wavelength of the measurement light on a basis of a detection result; a storage unit to store spectral characteristic information on possible background light, the information indicating a spectral characteristic of the possible background light, which involves a spectral sensitivity characteristic of the detection unit; and a processing unit to obtain a spectral characteristic of background light emitted from the ambience of the measurement object, from the measurement light spectral characteristic and the spectral characteristic information on the possible background light.
