It was great to see so many interesting and unique presentations at the International Optical Design Conference (IODC). IODC, held as a virtual event this year from June 27-July 1, took place as part of the OSA Optical Design and Fabrication Congress. Under the circumstances, OSA did a great job making the process of finding the talks of interest in each session possible!
Freeform designs – specifically, transmissive designs — have caught my attention lately. The presentation Motoyuki Otake of Sony Group Corporation, “Aberration Analysis of Zoom Lens System with Freeform Surface Lenses Using XY Polynomial,” was particularly interesting. Mr. Otake and his co-authors were able to demonstrate a very nice zoom freeform design and sensitivity analysis for an Alvarez-style system. You can view the presentation recording on the OSA website if you were registered for IODC – check it out if you missed it!

Watch this and other interesting talks on the OSA website while they are still available – a lot of exciting and interesting work is being done in optics and system design, and this year’s Optical Design and Fabrication Congress did not disappoint in sharing great projects from a wide range of engineers, students, and scientists in the field.
