Paper Abstract

The CIRS instrument to be flown on the Cassini mission to Saturn is a cryogenic spectrometer with far-IR (FIR) and mid-IR (MIR) channels. The CIRS FIR focal plane consists of focussing optics, an output polarizer/analyzer which splits the output radiation according to polarization. The reflected and transmitted components are imaged by concentrating cones onto gold black foil thermopiles. The focal plane covers the spectral range of 10-600 cm(-1). The geometric field-of-view requirement is 4.3 mrad. This paper details the assembly, alignment, characterization, cryogenic testing, and flight qualification of the CIRS FIR focal plane.
