Spectrometric instrument

A spectrometric instrument comprising:

• a light source;
• a light source drive section including a power control section adapted to control drive power of the light source;
• a measurement optical system including a spectroscopic section adapted to disperse light into wavelengths;
• a light receiving section adapted to receive one of a reflected light beam and a transmitted light beam from a sample as a measurement object passing through the measurement optical system, and converting the light beam received into an electrical signal;
• and
• a measurement section adapted to measure a light receiving intensity corresponding to each of the wavelengths of the light beam based on the electrical signal obtained from the light receiving section,
• wherein the power control section varies the power to be applied to the light source between the wavelengths in accordance with at least one of spectral characteristics of the light source, spectral characteristics of the measurement optical system, and light receiving sensitivity characteristics of the light receiving section.
