TMT Quality Assurance and Safety engineers Bryan Smith and Robert Anderson, accompanied by IIA Postdoctoral Fellow Dr. Vineeth Valsan and IIA Optics Engineer Manoj visiting the construction of the new optics facility dedicated to TMT primary mirror segment production.
The mirror blank was stored in a 20 feet container by NYK line, one of Japan’s biggest shipping companies, and transported by sea from Tokyo to Chennai via Singapore. The mirror blank arrived at the Centre for Research and Education in Science and Technology (CREST) on December 1, 2017.

Meeting of the IRIS team in Pasadena, CA in Sept 2017 to finalize the preliminary design review phase of the infrared imaging spectrograph (IRIS), which is one of TMT's first light instruments
The metrology device used in the polishing process of Roundel production - Two Dimensional Profilometer (2DP) owned and operated by Coherent Inc - is shown above in a special-use case where it is validating the active warping of the Polished Mirror Assembly (PMA).
Image of TMT type 82 prototype roundel, successfully polished at Coherent Inc. using the SMP process. It is the most aspheric mirror element of TMT’s primary mirror array.
