Scientific paper

Tinsley, under subcontract to Ball Aerospace, is optically finishing JWST’s secondary mirror, plus 18 precise lightweight beryllium mirror segments that constitute the surface of JWST’s 6.5m wide primary mirror. In this incremental paper, we emphasize the Tinsley transition from working a single engineering development unit to simultaneously fabricating pathfinder segments and other flight segments under coordinated requirements. Procedures and quality systems have been upgraded to address robustness appropriate to safely and simultaneously address this quantity of large high value beryllium mirrors. We summarize the suite of fabrication, handling, processing and metrology facilities satisfying the requirement flow down for the JWST flight optics. Approaches specific to JWST mirrors will be emphasized.
