We are excited to invite you to Vienna, renowned for its cultural richness and recognized as one of world’s foremost hubs of musical excellence, to join us in the CIE’s Midterm Meeting 2025!

The CIE Midterm Meeting features the Scientific Conference CIE 2025, to be held from July 7-9, 2025. This three-day conference brings together the CIE community and its stakeholders to advance the science of light and lighting, as well as the technical and organizational work of the CIE. The scientific conference will be preceded by the CIE General Assembly and other administrative meetings from July 4-6, 2025, and followed by the CIE Division and Technical Committee (TC) meetings on July 10th and 11th, 2025.

At the upcoming conference, all six scientific Divisions will discuss crucial topics, including the impacts of the digital age and artificial intelligence on lighting, controls, and measurement. Discussions will also explore the application of cone fundamentals in understanding light perception, alongside addressing the health impacts of temporally modulated light and glare, evaluation of virtual and augmented reality displays, and efforts to minimize obtrusive light and sky glow, reflecting CIE's global commitment to advancing light and lighting technologies.
