The Thirty Meter Telescope (TMT) will be the world’s most advanced and capable ground-based optical, near-infrared, and mid-infrared observatory. It will integrate the latest innovations in precisions control, segmented mirror design, and adaptive optics. At the heart of the telescope is the segmented mirror, made up of 492 individual segments. Precisely aligned, these segments will work as a single reflective surface of 30m diameter.

The TMT project is an international partnership between CalTech, Universities of California, Canada, Japan, China and India.
