We demonstrate continuous infrared spectra from 20 nm sample spots, by combining dispersive Fourier-transform infrared spectroscopy (FTIR) with scattering near-field microscopy (s-SNOM). As a next step we aim for spectroscopic near field images with 20 nm spatial resolution, at 6 cm-1 spectral resolution. The method is to be applied for biomedical imaging.
