12 October 2004 Mirror requirements for SAFIR
Author Affiliations +
Large-aperture lightweight low-cost cryogenic mirrors are an enabling technology for planned infrared, far-infrared and sub-millimeter missions such as CMB-POL, SAFIR, TPF-I and SPECS. This paper examines the mirror requirements for such telescopes and issues associated with their design, manufacture and test. Candidate mirrors must be able to survive launch and operate at temperatures below 10K. They must have a surface figure error of 1 mm rms, an areal density of less than 10 kg/m2, apertures of 1 to 2 meters and an areal cost of less than $500K per square meter.
