Abstract:
Spectrometer with an optical arrangement for capturing light to be measured and for splitting said light into spectral portions, said optical arrangement comprising: a light entry, a reflecting diffraction grating; a light exit surface through which the spectrally separated measured light exits, and a carrier body which is at least partly transparent and which is defined by two opposite end surfaces with the light entry, the reflecting diffraction grating and the exit surface being provided on a first of the two end surfaces of the carrier body, and a second of the two end surfaces including a reflective concave mirror for collimating the entering light and reflecting the light onto the reflecting diffraction grating and focusing light diffracted by the reflecting diffraction grating onto the exit surface, the light entry and the exit surface being spaced apart and a dispersion of the light in the exit surface being perpendicular to a line connecting the light entry and the exit surface.
