Abstract

A spectrometer assembly (10), comprising an Echelle grating (18; 46) for dispersing radiation entering the spectrometer assembly (10) in a main dispersion direction, and a dispersion assembly (16; 40) for dispersing a parallel radiation bundle generated from the radiation entering the spectrometer assembly in a lateral dispersion direction, is characterized in that the dispersion assembly (16; 40) is reflective, and the dispersion assembly (16; 40) is arranged relative to the Echelle grating (18; 46) in such a way that the parallel radiation bundle is reflected in the direction of the Echelle grating. The Echelle grating (18; 46) may be arranged in such a way that the dispersed radiation is reflected back to the dispersion assembly (16; 40).
