The Stratospheric Observatory For Infrared Astronomy (SOFIA) currently under development will mount a 2.5-m aperture IR telescope on an airborne (B 747 SP) platform for observations, at altitudes in excess of 12.5 km, in the sub-mm to visible spectral range. The first part of this work discusses the design tradeoffs which arose during the predevelopment phase in such considerations as primary mirror size and overall configuration. The second part gives attention to the incorporation of such advanced technology features as the thin Zerodur meniscus mirror concept used for the six-mirror compound telescope configuration, and the CFRP materials of the support structure.
