Paper Abstract

An optical test Dewar has been constructed with the unique capability to test mirrors of diameter <EQ 1 m, f <EQ 6, at temperatures from 300 to 5 K with a ZYGO Mark IV interferometer. The facility possesses extensive thermometry throughout for characterization of the test chamber thermal environment and Dewar performance. Optical accesss is controlled with cryogenically cooled shutters. The entire Dewar is vibration isolated by 40 dB where the fundamental resonances of the Dewar structure are highest. The facility has been brought on line for its first user, the Infrared Telescope Technology Testbed for the Space Infrared Telescope Facility at JPL. The design requirements for this facility and the resultant design and implementation experiences and challenges will be presented.
