A device for holding an object under a vacuum and processes for making the device, which may find application to uncooled infrared detectors. In the device, a leak tight cavity that contains the object, and in which the vacuum is created, and a getter designed to trap gases that could be located in the cavity are formed. The getter is placed outside the cavity and is contained in a leak tight housing connected to the cavity through at least one leak tight passage.

Device for maintaining an object under vacuum and methods for making same, use in non-cooled infrared sensors

A device for the detection of multi-spectral infrared and visible radiation using a bolometric detector having at least one active layer and two control electrodes for the detection of both infrared and visible radiation, and also using at least one photodetector having at least two active layers and two control electrodes for detecting solely visible radiation. The device is uncooled, and the two detectors are superimposed and combined with one-another for forming the same sensitive element.
