Pasadena, CA - Production of TMT’s polished glass-ceramic (M1 roundels) is ramping up according to plan. Coherent technicians and engineers have been busy polishing more roundels over the summer. Four new TMT primary mirrors underwent verification activities to meet TMT’s requirements. The new M1 roundels successfully passed inspection, including an on-site examination in August.
Bob Anderson, TMT Quality Assurance Group Leader, and Coherent quality assurance inspector performed a source inspection of the new TMT roundels. TIO validated the cosmetic surface inspections made by Coherent inspectors.
Following the source inspection, the roundels were carefully moved into their individual storage containers before being transported to the TMT warehouse in the Bay Area. At this time, TMT has a total of 10 Coherent roundels ready for the next production stage, Hex-cutting.
