INFRARED IMAGE PICKUP DEVICE

摘要

PURPOSE:To obtain a vacuum vessel for infrared image pickup devices which has a high cooling efficiency and in which numerous wires are fixed and the occurrence of disconnection and fault connection of the wires are prevented even when the vessel is subjected to shocks and vibrations. CONSTITUTION:A cold head 4 for mounting an infrared image pickup element 5 is put on the top of the inner cylindrical body 1 of a vacuum vessel 3 constituted in a double-pipe structure of the inner and an outer cylindrical bodies 1 and 2. A cylindrical body 11 formed of a porous sintered member is put around the cylindrical body 1 and wires 6 lead out from the element 5 are buried in the cylindrical body 11 or passed through a through hole formed through the cylindrical body 11.
