"The detector is cooled by a Stirling micro-cooler. This cooler, which operates on the basis of the Stirling circular process (isothermal compression and expansion), cools the detector within minutes to –196° C."

stirling engines, my dad showed me and taught me all sorts of things about thermal transfer when i was a kid. this was one application of them.
yea it'd be the shit to put on a cpu/gpu to keep it cooled, so far noone has. probably because the units would cost more then the components inside. its typical of all FLIR devices nowadays, at least the really decent ones that need accuracy and not just used for display.
