    The Priceless Mirrors


    There is a group of people creating mirrors at the University of Arizona. They sometimes spent 7 years to produce a mirror. These mirrors enable unique and powerful optical systems such as (1) Giant Magellan Telescope, a 25m camera; (2) Large Synoptic Survey Telescope, an 8.4m action-cam; and (3) Daniel K. Inouye Solar Telescope, a 4.2m microscope.Various new fabrication and testing technologies advancing the CCOS (Computer Controlled Optical Surfacing) process have been researched, developed and implemented to manufacture those highly aspheric/freeform optics.The materials, technology, time and efforts (a.k.a. inputs) are expensive, but the outcome is priceless. The story of amazing people creating the mirrors will be presented.

    Speaker Bio(s): 

    Dae Wook Kim is Assistant Professor at the College of Optical Sciences, University of Arizona. He graduated in Physics and Astronomy, Yonsei University, South Korea in 2003. He earned his Master’s and PhD degrees in the College of Optical Sciences, University of Arizona, USA in 2008 and 2009. He is currently a principal scientist for projects that develop and implement advanced technologies for building and testing large optical systems and astronomical telescope mirrors.He has been working in the optical engineering field for more than 10 years, focusing on very large astronomical optics such as 25m in diameter Giant Magellan Telescope primary mirror and 4.2m Advanced Technology Solar Telescope primary mirror. His main research area has been over the precision optical fabrication field. He is also working on various optical metrology topics such as interferometric testing using computer generated holograms, direct curvature measurement and deflectometry systems.He is teaching a graduate course “Fundamentals of Applied Optics Laboratory” at the University of Arizona, and has been served as a co-lecturer for “Computer Generated Holography and Diffractive Optical Elements Workshop” co-sponsored by SPIE. He has been authored/co-authored more than 30 journal articles and conference proceedings including some cover-featured, invited or the most downloaded papers.He is currently a chair/co-chair of the International Symposium on Optical Engineering + Applications, Optical Manufacturing and Testing (SPIE), the International Symposium on Optoelectronic Technology and Application, Telescopes and Large Optics (SPIE, OSA and Chinese Society of Astronautics), and the Topical Meeting on Optical Fabrication and Testing of the Optical Society of America (OSA). He is an Associate Editor for Optics Express journal.
