2026 Conference Program Available
The preliminary program for Nonimaging Optics: Efficient Design for Illumination and Concentration XXI in San Diego is now available.
The schedule includes sessions on nonimaging theory, solar concentration and receivers, thermophotovoltaics, radiative cooling, LED optics, illumination applications, and the 2026 optical design competition.
If you want to participate in this program, we will consider post-deadline abstracts through 29 June 2026. These submissions will be considered for the poster session, or for an oral session if space becomes available.
