One of two flight qualified beryllium 0.5 m diameter F/6 Cassegrain telescopes from the Modified InfraRed Interferometer Spectrometer (MIRIS) project is baselined to be flown on the Cassini mission as part of Composite InfraRed Spectrometer (CIRS) instrument. The imaging requirement for the CIRS telescope, 80% ensquared energy within 500 microns, is more stringent than that for MIRIS (95% encircled energy within 0.9 mm). Because the MIRIS telescopes had never been tested at cryogenic temperatures, only ambient data existed for these subsystems. A 0.864 meter liquid nitrogen dewar is being modified and will be used to perform in-house double pass and single pass ensquared energy tests of the beryllium telescopes at 170 K. This paper summarizes the ambient and cryogenic optical tests performed, the results and the status of the new cryogenic facility.
