James Webb Space Telescope optical telescope element mirror development history and results

摘要

In a little under a decade, the James Webb Space Telescope (JWST) program has designed, manufactured,assembled and tested 21 flight beryllium mirrors for the James Webb Space Telescope Optical TelescopeElement. This paper will summarize the mirror development history starting with the selection ofberyllium as the mirror material and ending with the final test results. It will provide an overview of thetechnological roadmap and schedules and the key challenges that were overcome. It will also provide asummary of the key tests that were performed and the results of these tests.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
