Abstract
segment handling system. The technical requirements for the STR system are very challenging on its
performance and interface condition with telescope-mounted optics and observation instruments. The major
challenging technical requirements include low flexure of mirror support structure, high seismic performance against
large earthquake, and fast, safe and labor-saving segment exchange. To meet these technical requirements, Mitsubishi
Electric Corporation (MELCO) has made a detailed design and technology development. In this paper, overview of
major key technologies is introduced that is adopted for the TMT telescope structure in the detailed design and
technology development, including recent prototyping of Pintle Seismic Isolation System.
Key Words: Telescope Structure, Low Gravitational Deformation
