Abstract
Calibrating a spectrometer module includes performing measurements using the spectrometer module to generate wavelength-versus-operating parameter calibration data for the spectrometer module, performing measurements using the spectrometer module to generate optical crosstalk and dark noise calibration data for the spectrometer module, and performing measurements using the spectrometer module to generate full system response calibration data, against a known reflectivity standard, for the spectrometer module. The method further includes storing in memory, coupled to the spectrometer module, a calibration record that incorporates the wavelength-versus-operating parameter calibration data, the optical crosstalk and dark noise calibration data, and the full system response calibration data, and applying the calibration record to measurements by the spectrometer module.
