Nonimaging Optics: Efficient Design for Illumination and Solar Concentration is a technical conference that convenes researchers, engineers, and designers working on the theory and practical implementation of nonimaging optical systems for lighting and solar energy collection. Held at the San Diego Convention Center, the meeting focuses on design methods, optimization techniques, and system-level applications that improve illumination efficiency and solar concentration performance. It is notable for its applied, interdisciplinary emphasis on translating nonimaging-optics theory into real-world lighting and renewable-energy solutions.
