The invention relates to a spectrometric measuring head for harvesting machines and other agricultural application machines, comprising a housing (1), provided with a window (2), in which an illumination source (3), a spectrometer arrangement (4) and at least two standards (5) for internal recalibration are provided. Said standards (5) can optionally be pivoted into the beam path of the measuring head such that all the measuring light emitted by the illumination source (3) is used for recalibration and a processor (11) for recording and processing the measured values and an interface (12) to a bus system are arranged in the housing (1). |
