Abstract

An optical component for an attenuated total reflection multispectral imaging device, which includes a support substrate and at least two planar waveguides, and wherein the planar waveguides and the support substrate are superimposed together, with the support substrate which covers the planar waveguides; each of the planar waveguides includes at least one diffraction grating; and at least two of the planar waveguides have their diffraction gratings which have values of the average pattern distribution pitch which are distinct from each other; the support substrate includes, on one side opposite the planar waveguides, a face forming an exchange interface with a sample; and an exit face of the optical component corresponds to a lateral face of the support substrate.
