A device for multispectral imaging in the infrared, suitable for detecting at at least one first and one second detection wavelength is provided. It comprises a detection matrix array comprising a set of elementary detectors of preset dimensions forming an image field of given dimensions; and an image-forming optic having a given aperture number (N) and a given focal length (F), which aperture number and focal length are suitable for forming, at any point of the image field, an elementary focal spot covering a set of at least two juxtaposed elementary detectors. The device furthermore comprises a matrix array of elementary metal-dielectric guided-resonance filters, which matrix array is arranged in front of the detection matrix array at a distance smaller than a focal depth of the optic, the dimensions of the elementary filters being such that each elementary focal spot formed at each point of the image field covers at least two elementary filters; and the elementary filters are optimised for pass-band transmission in spectral bands centred on two different central wavelengths, equal to two of said detection wavelengths.
