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.

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
Logan’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.

Marck Quezada’s (San Miguel High intern) Optical Science Kits
The CWSP program at San Miguel High School allows students to gain work experience that will benefit them in the future. Marck Quezada, a senior at San Miguel High School, joined LOFT group as an internship student in 2021-2022, worked with Daewook, and conducted a video of how optical science can be connected to anything around them because many people are unable to view optical science in their surroundings, Marck presented two instances of how optical science might be experienced from the comfort of one’s own home.
Vedant Janapaty’s (Silver Creek High School) Python Coding Project
Hello, my name is Vedant Janapaty and I worked on a research project with Professor Daewook Kim at the University of Arizona. Our project simulated Snell’s Law using Python Code. Snell’s Law is a formula used to describe the relationship between the angles of incidence and refraction, with regards to light. This project sought to plot both reflection and refraction using python code. The initial code accounted for refraction, the ability for light to pass through the surface. I extended this code to account for reflection. My results are summarized in this video. The original Python code is from the Vlabs project.
