A new concept of fully scanning multimodal micro-spectroscopy is presented, for simultaneous detection of Brillouin and Raman light scattering in a wide spectral range, from fractions of GHz to hundreds of THz. It yields an unprecedented 150 dB contrast, which is especially important for the analysis of opaque or turbid media such as biomedical samples, and a spatial resolution on sub-cellular scale. We report applications of this new multimodal method to a range of systems, from a single cell to the mechano-chemical mapping of highly scattering heterogeneous media.
