Abstract

In precision optical testing, it is desirable to provide a unified metering structure between the optical test source and the test article to limit the effects of incoming vibration sources. In this manner, the entire optical test structure may be vibration isolated as a single unit. Cryogenic temperature requirements for the James Webb Space Telescope make it cost prohibitive to maintain a single optical metering structure. This paper demonstrates the advantages and challenges of separately isolating the test source from the telescope, while using the Johnson Space Center Vacuum Chamber A as the metering structure supporting the two isolated assemblies.
