Abstract

The present disclosure includes a spectrometric measuring device for a measurement point of the process automation system, including a broadband light source for radiating light through an entrance aperture onto a sample to be measured, wherein the beam bundles of the light form an irradiation plane, a light limiter that limits the light at an angle to the irradiation plane, whereby a different amount of light results at this angle. The device further includes a dispersive element for separating the light according to its wavelength and a detector for receiving light separated according to its wavelength, wherein the light source beams the light through the sample to the entrance aperture, the light limiter and the dispersive element, and the light strikes the detector.
