Abstract
The twin composite structure telescopes aboard the Microwave Anisotropy Probe were selectivity roughened to reduce focused solar radiance. They were then overcoated with evaporated A1 + reactively evaporated silicon oxide films whose respective thicknesses were sufficient to achieve the high reflectance of bulk aluminum at the microwave operating frequencies; high emittance in the thermal emittance region; and moderately low solar absorptance for a resultant (alpha) /(epsilon) < 0.9. This report will discuss the experimental techniques used to prepare the telescope reflector surfaces and to evaluate their resultant properties.
