Abstract
A method for manufacturing a multispectral filter for electromagnetic radiation including two colour filters each including a first reflective layer, a second reflective layer, a layer of dielectric material of Fabry-Perot cavity, the thickness of the dielectric layer of both colour filters being different and each of both filters facing a photoelectric transducer. The method includes depositing a resin layer onto a handle substrate, structuring the resin layer to obtain two resin patterns of different heights, at least one of the patterns having a maximum reference height; depositing a dielectric layer to form the dielectric patterns of the Fabry-Perot cavities and planarising; transferring the planarised face of the handle substrate to the upper face of a carrier substrate; removing the handle substrate and the resin and depositing a reflective layer onto the at least two dielectric patterns of Fabry-Perot cavity, forming the second reflective layer.
