The present invention is directed to a grating spectrometer system for polychromator spectrometer arrangements and monochromator spectrometer arrangements. The grating spectrometer system, according to the invention, comprises a light source for illuminating the sample to be analyzed, a diffraction grating, imaging optical elements, a detector arranged in the image plane, and a controlling and regulating unit. Individual light sources, preferably LEDs having different spectral characteristics, whose spectral range covers a plurality of diffraction orders in the image plane are used as light source. Only those LEDs which do not illuminate the same location of the individual detectors arranged in the image plane in any diffraction order are switched on individually or in groups by the controlling and regulating unit. The proposed solution is suitable for polychromator spectrometer arrangements and for monochromator spectrometer arrangements. The field of application is determined by the spectral sensitivity of the detector that is employed. By using a plurality of diffraction orders, the resolution can be increased with the detector size remaining the same, or the detector surface can be reduced while retaining the same imaging quality.

Grating spectrometer system and method for the acquisition of measured values

An arrangement for measuring the diffuse reflection of samples and a method for internal recalibration of the measuring head. The spectrometric measuring head with a device for recalibration comprises a housing which is provided with a window and which contains an illumination source, a spectrometer arrangement and at least two standards for internal recalibration. The two standards can be swiveled into the beam path of the measuring head selectively so that the measurement light emitted by the illumination source can be used in its entirety for recalibration. A processor for acquiring and processing measured values and an interface to a bus system are arranged in the housing. Accordingly, relatively time-consuming calibration of the measuring head at the place of use is required only before putting into operation or at longer time intervals. By the internal recalibrations, it is possible to prevent changes in the measured values in long-term operation.
