Abstract
An infrared cold shield comprises a side wall, a top wall and at least one baffle extending across the interior of the cold shield. The top wall and baffles comprise aligned apertures. The cold shield is preferably made by securing one or more metal foil disks and aluminum mandrel segments in an alternating stacked arrangement wherein the outer edges of the metal foil disks are exposed. The assembly is then electroplated to deposit a layer of metal over the side surfaces of the mandrel segments and to capture and bond with the exposed edges of the metal foil sections. The mandrel segments are then dissolved.
Claims11
A one-piece cold shield comprising a side wall and a top wall defining an interior chamber, an aperture through the top wall and at least one baffle extending transversely across the interior chamber of the cold shield, said at least one baffle comprising an aperture in alignment with the aperture of the top wall and wherein the outer edge of the at least one baffle is encapsulated by and metallurgically bonded to the side wall.
A one-piece cold shield comprising a side wall and a top wall defining an interior chamber, an aperture through the top wall and at least one baffle, the outer edge of which is encapsulated by and integral with the side wall, said at least one baffle extending transversely across the interior chamber of the cold shield and comprising an aperture in alignment with the aperture of the top wall.
A one-piece cold shield comprising a side wall and a top wall defining an interior chamber, an aperture through the top wall and at least one baffle, the outer edge of which is encapsulated by and electrolytically bonded to the side wall, said at least one baffle extending transversely across the interior chamber of the cold shield and comprising an aperture in alignment with the aperture of the top wall.
