Abstract (en)
[origin: WO2017121583A1] A spectrometer assembly (10) with a two-dimensional spectrum comprising a first dispersing element (31) for the spectral decomposition of radiation in a main dispersion direction, an imaging optical system (17) for imaging in an image plane the radiation penetrating through an inlet gap (15) in the spectrometer arrangement (10) and enabling a two-dimensional spectrum to be produced, and a surface detector (39) with a two-dimensional arrangement of a plurality of detector elements in the image plane. Said spectrometer assembly is characterized in that a reflector, a refractor, a lens array or another optical element is arranged in the beam path at a point where the dispersed, monochromatic bundles are present in a separated manner, and the reflector, the refractor, the lens array or the other optical element have a surface in the form of a free-form surface wherein the surface occupied by the selected images of the inlet gap at different wavelengths in the image plane is optimised over a selected spectral range of the two-dimensional spectrum.
