Dewars take heat from infra-red
If you can't stand the heat ... cool it with liquid nitrogen
The new dewars can accommodate the company's full range of photovoltaic and photoconductive IR detectors as well as IR LED's for operation at liquid nitrogen temperature (77 K). The standard model has a liquid nitrogen 'hold' time of more than 8 hours (12 hour dewars offered as options) and incorporates six electrical leadouts within a permanently mounted connector box and cover plate. Individual and multiway connectors can be accommodated.
The dewars are supplied with a choice of anti-reflection coated and uncoated windows which may be either narrow band or broadband for thermal radiation.
