SPIE Instructional Webinar by Daewook Kim

Daewook Kim will provide an SPIE Instructional Webinar “Optical Testing for Ground and Space Telescopes” on 27 July 2021. The recorded Webinar is available at the SPIE webpage.

SPIE Press book chapter authored by Daewook, Logan, and Isaac


Daewook Kim, Logan Graves, and Isaac Trumper wrote a book chapter “Metrology” for the SPIE Press Book “Review of Optical Manufacturing 2000 to 2020” edited by Aizhong Zhang and Richard N. Youngworth. This book summarizes some of the critical changes that have impacted optical system manufacturing from 2000 to 2020. It evaluates new manufacturing techniques with growing popularity and identifies future trends. The chapters provide a snapshot of the field that conveys the basics of current manufacturing capabilities and promising new techniques. Other topics reviewed include optical materials, optical fabrication, metrology, optical coatings, infrared optical systems, polymer optics, fiber optics, diffractive- and micro-structured optics, and illumination optics. This book is suitable for beginner optical engineers learning about the optics industry and for advanced professionals staying up-to-date with various subfields of optics.

This week’s Watts Up Historical Lens finds focus on OSC’s past alumni. Peruse a collection of thoughts and pictures generously shared with OSC Historian, Tammy Orr, as we walk down memory lane through the eyes of twenty-nine OSC graduates including LOFT peer Dae Wook Kim.

Phys.Org Article: A new lens for life-searching space telescopes

Please, read this article explaining the new space telescope concept called Nautilus project. LOFT group is a happy member of the project team.

Dae Wook explaining the GMT2 manufacturing

“Each of the GMT’s seven primary mirrors is 8.4 meters in diameter and takes approximately four years to create. The final stage of work for segment 2 — front surface polishing — took just ten months, significantly faster than for segment 1 due to new polishing and metrology techniques invented at the University of Arizona. With these techniques established, future GMT mirrors should pass through the pipeline faster. Watch a short interview with Dr. Dae Wook Kim of the University of Arizona where he explains these techniques.” Also, please, read the full GMTO Newsletter article here.

Erika on TED (Hyperion Project PI)

Hyperion UV space telescope project team PI, Erika (CC’d), gave a fantastic talk at the TED event. Three LOFT peers, Heejoo, Hyukmo, and Yi-Ting, recently made great contributions for the Hyperion optical system design and analysis. We are happy for our awesome team with great PI and talented colleagues! Congratulation, Erika!

OSA Spotlight on Optics highlights Logan’s (LOFT member) paper 

osa-spotLogan’s recent Optics Express publication, “Infinite deflectometry enabling 2pi-steradian measurement range,” has been chosen for the OSA Spotlight on Optics. Here is a message from OSA. “Spotlight on Optics showcases research produced in out journals-research and information that would be impossible without your talent and contribution. Your paper is in excellent company. Only two papers are highlighted from our respective journals each month from among the scores of fine articles published.” We are happy for this academic contribution from our member recognized by our community.

Optics Outreach Abroad – Chile 2011 – Opening Video

The Astronomical Optics Workshop is an initiative of the Student Optics Chapter and the College of Optical Sciences at the University of Arizona together with the Pontifical Catholic University of Chile. The 4-day workshop focuses on geometrical optics, aberrations, diffraction, and opto-mechanics, emphasizing their applications for telescopes, instrumentation, and any other opto-mechanical system.

Additionally, the program features outreach to several high schools in Santiago with the goal of motivating young students in the sciences and optics and inspiring their participation in the future of astronomy and optics in Chile.
