Paper Abstract

Abstract. The design of an operational mount to rigidly secure the primary mirror to its baseplate without the introduction of figure error always proves to be a major task on diffraction limited optical systems. A summary of the design of the Infrared Astronomical Satellite (RAS) primary mirror mount is given. The mirror was designed to be aligned and tested at room temperature and operated in a zero "g"field at temperatures of 2 Kbo minimize overstressing, a stiffness requirement of greater than 150 Hz was required for cold launch and room temperature vibration acceptance testing. Additional isolation was required to minimize strains, introduced via the mounting base, due to thermal and mechanical distortions.
