"Optics for the Giant Magellan Telescope"

Seminar by

Dr. Jim Burge,
University of Arizona


Abstract: The University of Arizona has started making the optics for the Giant Magellan Telescope -- an astronomical telescope with 25 meter aperture.   The giant primary mirror for GMT will be made of seven smaller pieces, each 8.4 meters across.  The effects of the atmosphere will be measured using laser guide stars and will be corrected in real time by deforming the 4 meter secondary mirror.   The challenges of making the telescope optics are being directly addressed at the University of Arizona.  This talk will summarize the design and performance of GMT and will discuss the technology for the mirrors.

BIOGRAPHY: Dr. Jim Burge is Associate Professor at the University of Arizona with joint appointments at the College of Optical Sciences and Steward Observatory.  He has led the development of optical testing and mirror fabrication technologies that enable the production of large, highly aspheric telescope mirrors. He also leads a group of graduate researchers and teaches courses in applied optics and optomechanics.
