Variable Focal Length High Speed Lens

Abstract

This report describes the development and prototype manufacture of a high speed (f/2.4) zoom lens to work in the near infra-red (0.7 to 0.9mm) in conjunction with an image tube night viewing system. The development or design effort covered a period of 32 months and proved to be a very difficult design problem which required the performance objectives (specs) to be modified somewhat in order to permit the realization of a successful design. The completed design was fabricated (in 17 months) as a bench model prototype and found to meet the expected performance values. This unit was delivered for final testing in December 1971.
