The electromagnetic radiation detection device includes, on a same substrate: at least one active detector of the electromagnetic radiation provided with a first element sensitive to said radiation, at least one reference detector including a second element sensitive to said electromagnetic radiation, and a lid provided with first reflective means reflecting the incident electromagnetic radiation, said lid covering without contact the second sensitive element and defining with the substrate a cavity having the reference detector housed therein. The lid is designed to improve the sensitivity of the detection device.
