A multispectral filter matrix for an electromagnetic wave, the matrix including at least a first and a second optoelectronic element, each optoelectronic element including a colour filter and a photoelectric transducer facing the filter, each colour filter forming a Fabry-Perot cavity including a first reflective layer, a second reflective layer and a Fabry-Perot cavity layer of dielectric material between the first reflective layer and the second reflective layer, the layer of dielectric material including a lower surface, in contact with the first reflective layer; the lower surface being curved, an upper surface in contact with the second reflective layer, the upper surface being curved, the average thicknesses of the two layers of dielectric material of the two filters being different.
