Abstract:  Cost and cost credibility now match performance in importance as criteria underlying most space mission architectures.  This is especially true in the domain of optics and specifically optical telescope assemblies.  Whether a large NASA or ESA Observatory or a constellation of Earth Observing or Communication Satellites, at earliest stages of development design-to-cost (DTC) now enters the process.  When optical level dimensional stability is needed, material selection drives complexity, and as a corollary, cost and robustness.


Material selection also drives mass, though with advent of heavy lift launch vehicles, ultimate mass reduction is less important than in the past, though mass may still affect power and control stability. And mass remains a parameter in many parametric cost models used by evaluators.  My experience is expressed spanning 40 years in selection of optical materials constituting a systems parameter for space applications.  Lessons-learned are expressed with mirror materials from aluminum and beryllium to ULE and ZERODUR® and even CFRP.

 

About our speaker: Tony Hull was a Board Member of OSSC during several of his 24 years in Southern California while working at Perkin-Elmer (P-E), Optical Corporation of America (OCA) and Jet Propulsion Laboratory (JPL). Material optimization has consistently been one of his system’s development considerations. He served as NASA’s Technologist for Terrestrial Planet Finder Coronagraph. In Northern California, he became Director of Large Optics at Tinsley and Program Manager for the optical fabrication of the full suite of JWST beryllium mirrors. Presently Tony is Adjunct Professor of Physics and Astronomy at the University of New Mexico, continuing to support SCHOTT into a second decade of advancing lightweight ZERODUR® for critical spaceborne application.
