Abstract

A new generation of ultra-low power bolometer arrays is under development for low background infrared astronomy. This paper describes radiometric measurements on such bolometers using a cryogenic blackbody source with accurately calculable throughput. Because of the very long wavelengths used, roughly 100 5m - 1 mm, the absorbed radiant power differssubstantially from that in a classical radiometry measurement, where it would be given by the geometric throughput with small diffraction corrections.
