    Advances in our understanding of the Universe depend on improvements in sensitivity and angular resolution that can come only with larger telescopes. Telescope diameters increased by an order of magnitude in just over a century, but that growth has been sporadic, limited mainly by the ability to make bigger mirrors that hold their shape against the dynamic effects of gravity, wind and temperature. Three major advances in mirror technology occurred in the 1980s, including the lightweight honeycomb mirrors made at the Mirror Lab. I will describe these technologies, and show how they enabled the current generation of 8- to 12-m telescopes and how they are now being used to build telescopes of 25 to 39 m.

    Speaker Bio(s): 

    Buddy Martin is Project Scientist for Mirror Polishing at the University of Arizona’s Richard F. Caris Mirror Lab. He leads the fabrication and testing of large optics, including the 8.4 meter segments of the Giant Magellan Telescope. Buddy’s background as a radio astronomer before joining the Mirror Lab in 1986 helps maintain a passion for contributing to new telescopes and new discoveries.
