Abstract

123123123123A spectroscopic instrument (38) includes a first optical component (48) for spatial spectral splitting of a polychromatic beam of light (46) impinging onto the first optical component (48) an objective (50) which routes various spectral regions (B B B) of the split beam of light (46a 46b 46c) onto differing spatial regions (52a 52b 52c) and a sensor (54) situated downstream of the objective (50) in the beam path of the beam of light (46a 46b 46c) with a plurality of light sensitive sensor elements (54a 54b 54c). The sensor elements (54a 54b 54c) are arranged in the beam path of the split beam of light 46a 46b 46c in such a manner that each sensor element (54a 54b 54c) registers the intensity of a spectral sector (A A A) of the beam of light (46) and the medians (Mk Mk Mk) of the spectral sectors (A A A) are situated equidistant from one another in the k space where (k) denotes the wavenumber.
