The Stratospheric Observatory For Infrared Astronomy is a planned 2.5 meter telescope that will be installed in a modified Boeing 747 aircraft and operated at altitudes above 40,000 feet. A concept for the telescope optical assembly which includes the primary mirror, secondary mirror, tertiary mirrors, and the metering structure will be discussed. The optical assembly is modular to facilitate assembly/disassembly operations. The optical assembly will have an image quality of less than 1.5 arcseconds, operate at elevation orientations from 15 degree(s) to 70 degree(s), and reach thermal equilibrium at -40 degree(s)C in less than 2 hours. A passive lightweighted monolithic primary mirror design based on proven technology has been shown to be a key element in meeting these requirements.
