Abstract
In this novel multimodal wide-field Raman microscope, spectra are obtained by the time-domain Fourier-transform method. The wide-field approach enables faster collection of Raman maps, while the time-domain method disentangles fluorescence and Raman signals. This is obtained by choosing a proper sampling of the interferogram, thanks to the use of an ultrastable common-path birefringent interferometer. Validation of the system is performed on plastic microbeads; multimodality is demonstrated by fluorescence and Raman maps of a few-layers transition metal dichalcogenide sample.
