Abstract: A high-strength, single-staged, composite thermoelectric cooler (18) for stabilizing the temperature of an uncooled, infrared detector (16) comprising a pair of ceramic plates (20, 22), a plurality of thermoelectric elements (24) sandwiched between the plates (20, 22) such that the thermoelectric elements (24) and the ceramic plates (20, 22) define a plurality of chambers (26), and a thermoelectric insulator (28) which substantially fills the chambers (26) inside the thermoelectric cooler (18) forming a high-strength composite structure with the thermoelectric elements (24) and the ceramic plates (20, 22).

Abstract: A hermetically cold weld sealed package and method for sealing where a metal seal member 28 is placed along the edge of a base 36, an organic sealant 26 is placed along the outside of the base adjacent the metal seal member 28, and a lid 30 is placed over the base 36 to create a hermetically sealed cavity 46. The process takes place at room temperature environment in an inert environment, and on heating of the metal sealing member 28 is required. The shrinkage of the organic sealant 26 during curing applies pressure to the metal seal member 28, enhancing the effectiveness of the hermetic seal.
