摘要： The invention concerns an evanescent wave microspectrometer comprising: a planar diopter (D) separating two transparent media, an optical sensor (30) comprising a pixel array, and disposed in the second transparent medium (M2), and an interference device ((10, F1); (11, F1_1, F1_2)) disposed such that at least a part of said interference device is in contact with evanescent waves generated at the surface of the diopter. It is essentially characterised in that it also comprises: a memory storing a map (40) comprising a set of set of data grids (41, 42, 43) comprising the optical response of said sensor (30) for a set of quasi-monochromatic wavelengths of a calibration light source, and a calculator (50) configured to determine the spectrum (ψ) of a test light source configured to generate evanescent waves at the surface of said diopter (D), on the basis of said map (40) and the optical response of said sensor (30).
