Abstract
The invention concerns a detection device for detecting electromagnetic radiation, comprising a substrate, an array of thermal detectors, each thermal detector comprising a suspended absorbent membrane and a reflective layer. The detection device comprises at least one opaque vertical wall, arranged on the substrate and extending longitudinally between two adjacent thermal detectors, and produced from a material that is opaque to the electromagnetic radiation to be detected.
