<p>The excitation means comprise means for generating a plurality of monochromatic excitation beams (FEX1, FEX2) of different wavelengths, and transporting means for converging said plurality of excitation beams (FEX1, FEX2) on the same spatial region of the sample (ECH). The analysing arm comprises means for collecting the radiation (RD12) resulting from the illumination of said spatial region of the sample (ECH) by said plurality of excitation beams (FEX1, FEX2), and transferring said radiation (RD1, RD2, RD12) on to the spectral analysis means (ANA), means for detecting (DEC) and processing the spectra generated by said spatial region of the sample thus excited at different wavelengths.</p> |
