Abstract

The present disclosure relates to a spectrometer arrangement for analyzing optical radiation from a light source comprising an echelle grating for dispersion of the radiation entering the spectrometer arrangement in a main dispersion direction, a dispersion element for dispersing the radiation in a cross-dispersion direction, the main dispersion direction and the cross-dispersion direction having a predeterminable angle to each other, and a detector unit for acquiring a first spectrum of a first part of the radiation comprising a first predeterminable wavelength range. According to the present disclosure, the spectrometer arrangement comprises a first optical element, which is arranged or configured in such a way that a second spectrum of a second part of the radiation comprising a second predeterminable wavelength range differing from the first can be acquired by means of the detector unit.
