Abstract
A spectrometer includes: a diffraction means that diffracts light being measured which has entered via an entrance unit; a main sensor that receives the light being measured which has been diffracted by the diffraction means; at least one auxiliary sensor disposed in an optical path of a luminous flux that does not reach the main sensor among luminous fluxes that have entered via the entrance unit, the auxiliary sensor receiving the luminous flux; and a correction means that corrects an output value of the main sensor on the basis of an output value of the auxiliary sensor.
