Claim Text:
1. A spectroscopic device comprising: a lamp house accommodating a light source inside; a spectrometer positioned to receive light from the light source; temperature measurement means provided on the spectrometer, for measuring a temperature of the spectrometer; heating means provided on the spectrometer and configured separately from the lamp house, for heating the spectrometer; storage means for storing a detection temperature of the temperature measurement means at a time a base line of a chromatogram is stable in a state where the light source is illuminated; and a control unit configured to control an operation of the heating means, and to cause the heating means to operate, when the light source is illuminated from a light-off state, only until a detection temperature of the temperature measurement means reaches the detection temperature stored in the storage means.
