(Intentionally Dual-Use R&D is fascinating subject of its own. The CORONA satellite camera required a super-flat anti-astigmatic high-magnification lens. The ITEK Photo-Typesetting system was the dual-use cover, public-private partnership, and exploitation for the lenses' R&D. When CORONA finally was declassified, we had a nice presentation on this synergy from the ITEK type designer at The Museum of Printing.
