Paper Abstract

The Airborne Optical Adjunct (AOA) sensor mirrors' fabrication is addressed. Also reported are the final mirror figure quality achieved and the techniques used. The primary, secondary, and tertiary mirror figures are off-axis sections of high-order aspheric surfaces. The three mirrors are used as a wide field-of-view, non reimaging IR telescope. Such a complex system had never been constructed prior to the start of the AOA project. Production of these mirrors has pushed the state-of-the-art in fabrication technology. The mirrors were figured prior to being cut to size, lightweighted, and having precision mounts machined. Mirror figures were checked both mechanically and optically. Of special importance are problems overcome and lessons learned in this endeavor.
