Paper Abstract

This paper will review the particulate control program applied to the design, construction and testing of the Optical Telescope Assembly. Allowable levels of contamination were derived from system performance requirements using performance predictive models. These levels were used as guidelines in establishing control and monitoring procedures for the assembly process. Measurements taken at critical junctures indicated that cleaning of the optics was required. Cleaning operations were performed at the latest stage of assembly possible. Subsequent measurements verified the effectiveness of the procedures. Optical surface tests, conducted after Space Telescope environmental testing, revealed that the optical surfaces were well within acceptable limits.
