Spectrometer with an optical arrangement for the capturing of light to be measured and the separation thereof into spectral portions with a light entry, a reflecting diffraction grating and an exit surface from which the spectrally separated light to be measured exits, whereby the optical arrangement (O) includes an at least partially essentially transparent carrier body (T) which is defined by two opposite end surfaces (1, 2) whereby the fight entry (10), the reflecting diffraction grating (20) and the exit surface are located on the side of the first (1) of the two end surfaces (1, 2) of the carrier body (T) and the second (2) of the two end surfaces includes a reflective concave mirror, which collimates the entering light and reflects it onto the reflecting diffraction grating and focusses the light diffracted by the reflecting diffraction grating onto the exit surface, whereby the light entry (10) and the exit surface are spaced apart and a dispersion of the light in the exit surface (R) is at least about perpendicular to a line of connection between the light entry (10} and the exit surface.
