Abstract
A measurement device for spectroscopic constituent analysis includes a control unit, a light source, a sample holder arranged in the beam path of the light source, and a spectral measurement module. The measurement module comprises at least one photosensor with organic photodiodes arranged on a substrate and a temperature sensor arranged at the photosensor. During a sample measurement, a method using the measurement device comprises: detecting an actual temperature at the photosensor; pivoting-in a dark reference sample and measuring a dark reference value; pivoting-in a bright reference sample and measuring a bright reference value; measuring a spectral value of the sample and correcting the spectral value by means of a correction calculation by way of the control unit using the dark reference value, the bright reference value, the spectral value of the sample, the temperature and using values which were determined in a pre-calibration and stored in the control unit.
