DEVICE FOR MAINTAINING AN OBJECT UNDER VACUUM AND METHODS FOR MAKING SAME, USE IN NON-COOLED INFRARED SENSORS

摘要

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.
