CRYOSTAT FOR INFRARED RADIATION RECEIVER Russian patent published in 2010 - IPC F25B19/00 

FIELD: physics.

SUBSTANCE: cryostat has a housing with a cooled platform and a unit for cryostating the cooled platform. The cryostating is in form of a container which can be filled with liquefied gas and has a filler neck, on whose outer surface of which there is a cooled platform, or is docked with a micro-cryogenic cooling system in form of hands of the cryostat on which the cooled platform is placed. The filler neck or cryostat hands consist of three thin-walled coaxially arranged stainless steel pipes with a gap in between. The cooled platform made from copper is joined to the housing by suspending elastically stretched strings.

EFFECT: reduced heat leakages and high resistance to external mechanical effects.
