The Renishaw micro-Raman spectrometer is equipped with a reflected light microscope which enables a mini-analyzed area of 5 micrometres. The microscope is equipped with 5, 20, 50 times objectives and electrically adjustable sample stage. Excitation is accomplished at two laser wavelengths - either 488nm (blue, Ar ion) or 633nm (red, He-Ne). The resolution of Raman shift is 0.5 wave numbers.
