  • Patent number: 10739198
    Abstract: A polychromator includes a substrate and a functional element having an optical spectral decomposition action. The functional element having an optical spectral decomposition action is configured to spectrally decompose electromagnetic radiation originating from an entry opening, e.g. light which originates from an optional radiation source and is reflected at a sample, so that a spectrally decomposed spectrum is obtained, and to image the spectrally decomposed spectrum onto a spatial area of the substrate. The substrate includes at least two transparent zones at different positions within the spatial area, so that two different spectral components of the spectrums are detectable at the two transparent zones.
