The Laser Units (each consisting of a Laser Head and Laser Electronics) are installed on the laser platform. A long beam transfer optics enables the laser beams to be relayed to the LGSF Top-End, where they will be formatted and then launched from the laser launch telescope.

The LGSF mounted on the telescope structure will project powerful laser beams into the upper atmosphere of the Earth, creating artificial stars for adaptive optics correction of the atmospheric turbulence.

TMT refrigeration prototype for NFIRAOS first-light adaptive optics system has been developed by the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences (TIPC) in Beijing and arrived at the NRC Canada's Herzberg Astronomy and Astrophysics Research Centre in Victoria.

Opticaltestsystem
June 1st, 2021

Beam Launch and Imaging System (BLIS). The BLIS sub-system will be installed at the top of a five-story test for measurement of an M1 segment assembly below at the bottom of the tower. The side covers have been removed in the picture on the left, showing the mechanical setup and cable routing of the imaging and illumination system. At center, the access door allows the technician to exchange the computer-generated hologram (CGH) to match the type of M1 segment that is being measured.

The telescope structure system provides structural support and precise motion, and also space for accessing and servicing the telescope optics, their associated systems (M1S, M2S, M3S), the science instruments, adaptive optics systems, and auxiliary systems. STR cradles the TMT’s 492 articulated mirror segments as they relay the light of astronomical bodies to the M2 and M3 mirrors and finally to the several science instruments located on both lateral Nasmyth platforms

TMT STR serves as the skeleton and muscles of the telescope and thus interfaces with various instrumentation, optics, and controls subsystems. TMT STR will hold the TMT's optics and smoothly tracks celestial targets as they move across the sky. For perspective, the telescope is ~55m (180 feet) wide and ~50m (160 feet) tall.
