Grating spectrometer system and method for measurement recording

摘要

The system has a light source for lighting a sample (6) to be tested, where the source has individual light sources of different spectral characteristics. The spectral zone of the sources overcoats several diffraction orders in an image level. A control and regulating unit (8) switches the light sources individually or in groups, which do not light the same position of detectors arranged in the image level, in any of the arrangements. An independent claim is also included for a method for performing measurement value logging.
