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.

Artist rendering of TMT Observatory on the Observatorio del Roque de Los Muchachos (ORM) in La Palma. The image shows the operations facility adjacent to the telescope. A viewing gallery will be built next to the main entrance, within the facility building, available to all ORM visitors who want to see the giant telescope from up-close. ORM is the alternate site for the Thirty-Meter-Telescope; Maunakea, in Hawaii, still being currently the official site where TMT will be built.
