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.
