The first TMT primary mirror (M1) metrology frame has been built and delivered to TMT’s technical laboratory near Pasadena. TMT will use the metrology frames, which are auxiliary equipment tools, to accurately locate the M1 mirror segments during installation.
The first of TMT’s Primary Mirror (M1) segment prototypes was recently tested and polished using the Ion Beam Figuring (IBF) process.
The Multi-Segment Integration & Test (MSIT) facility at the TMT lab in Monrovia, California, is now fully populated with seven aluminum mirror segment prototypes.
One of TMT’s most important components – its huge primary mirror that spans over 30 meters – continues to be manufactured around the world.
Pasadena, CA, January 13, 2020 – The design of the Thirty Meter Telescope’s Tertiary Mirror (M3) recently passed the first part of its Preliminary Design Review, which took place over two days in November 2019.
Coherent Inc., one of the world’s leading providers of lasers and laser-based technology, is now ready to polish all of the TMT primary mirrors segments to be manufactured in the United States.
Two full-size TMT Primary Segment demonstration assemblies fitted with aluminum mirror segments have been successfully installed into the Multi-Segment Integration & Test (MSIT) facility at the TMT lab.
The leaf springs required for TMT warping harness mechanism, supporting each one of the 492 primary active segments, are being tested and validated in an Environmental Simulation Laboratory.
Work is underway at TMT Project Lab. near Pasadena.
Dr. Saku Tsuneta, Director General of the National Astronomical Observatory of Japan (NAOJ), recently met with TMT experts at the technical laboratory in Monrovia, California. Dr. Tsuneta also serves as a member of the TMT Board of Governors, which is accountable for both financial decision-making and strategic planning for the TMT International Observatory.
