Claim Text:
1. An analysis device for analyzing components contained in an object, the analysis device comprising: a light emitting unit that irradiates the object with light; a transmissive spectral filter; a light detector comprising a plurality of light receiving elements; an analysis unit, a beam splitter that splits light irradiated by the light emitting unit; and a reference sensor unit that receives the light split by the beam splitter and outputs a reference signal, wherein the beam splitter is disposed between the light emitting unit and the object, wherein the reference sensor unit includes: wherein the attenuating filter, the second spectral filter, and the second light detector are disposed such that the light split by the beam splitter is incident in order of the attenuating filter, the second spectral filter, and the second light detector, wherein a plurality of light receiving elements of the second light detector output signals according to incident light, and wherein the analysis unit corrects the output signal of each of the plurality of light receiving elements of the light detector based on the signals from the second light detector.
