Scientific paper

Tinsley, under subcontract to Ball Aerospace, is optically finishing JWST's 18 precise lightweight beryllium mirror hexagonal segments that constitute the surface of JWST's 6.5m wide primary mirror, plus the secondary mirror and tertiary mirror for this telescope. In this incremental paper, we emphasize Tinsley's preparation of mirrors for Ball Aerospace cryogenic metrology, which is the basis for final cryogenic-null finishing at Tinsley. Tinsley's approach to simultaneous optical finishing of a number of segments, and progress toward deliveries, will be summarized.
