Abstract
The invention concerns an electromagnetic radiation sensing device with integrated housing including two superimposed sensors. A first sensor detects one first wavelength range, and a second sensor detects a second wavelength range. The first sensor is arranged inside a protective housing, whereof at least the upper wall includes the second sensor. The wavelengths of the first range, for example included in the infrared domain are, preferably, greater than the wavelengths of the second range, which can be included in the visible or ultraviolet domain. The first sensor is, preferably, a bolometer comprising a sensitive elements and support element forming electrical connection elements between the first sensor and/or the second sensor and an electronic processing circuit.
