An apparatus for carrying out Raman spectroscopy on a sample includes a light source for providing a beam of excitation radiation, and an optical system including a spectrograph. The spectrograph includes a grating that divides a beam of scattered light into a spectrum of spatially separated wavelength components and to direct a portion of the spectrum to a detector. The spectrograph includes: 1) a first lens system for focusing the portion of the spectrum onto the detector and 2) a second lens system-configured to provide a focal plane with focal point in the optical path for focusing the beam of excitation radiation and/or the beam of scattered radiation at the focal point. The apparatus including a reference sample arranged in the focal plane, in particular at the focal point, for obtaining a reference spectrum from the reference sample.
