Abstract
A spectrometer arrangement with two-dimensional spectrum, comprising a first dispersing element for spectral separation of radiation in a main dispersion direction, an imaging optics for imaging the radiation entering into the spectrometer arrangement through an entrance slit in an image plane for producing a two-dimensional spectrum, and a detector array with a two-dimensional arrangement of a plurality of detector elements in the image plane, wherein a reflector, a refractor, and/or a lens array are arranged in the beam path at a location where the dispersed, monochromatic beams are separated from one another, and the reflector, the refractor, and/or the lens array have a surface in the form of a freeform surface, such that area occupied by selected images of the entrance slit in the case of different wavelengths in the image plane is optimized over a selected spectral region of the two-dimensional spectrum.
