Measuring apparatus and method for resolution spectral measurement of electromagnetic radiation

A device for spectrally resolving measurement of electromagnetic radiation, comprising: a two-dimensional detecting element with a first set of pixel elements for detecting a light incident on the first group of pixel elements the first part of electromagnetic radiation and a second set of pixel elements for detecting a light incident on the second group of pixel elements the second part of the electromagnetic radiation; and a band-pass filter element for spectral filtering of the first part of the electromagnetic radiation, which is arranged with respect to the first group of pixel elements, that the detection of the first group of pixel elements according to the spectral filtering of the first part of the electromagnetic radiation is carried out by the band-pass filter element and the detecting the second set of pixel elements without spectral filtering of the second part of the electromagnetic radiation is carried out by the band-pass filter element, wherein one pixel element of the first group of pixel elements corresponding toward and disposed in spatial proximity to a pixel element of the second set of pixel elements.
