This Symposium was organised by CIE Division 2 in cooperation with the Swiss Lighting Society (SLG), and was hosted by the Federal Office of Metrology (METAS), Bern, Switzerland. The two-day Symposium included a one day tutorial presenting the state-of-the-art techniques in the field of photometry. On the second day, a Scientific Symposium featured 35 contributed papers presenting recent research in photometry, colorimetry, and radiometry with a focus on the methods using spectral and imaging techniques. The Symposium had four sessions, Session I: Goniophotometry and Spatial Methods, Session II: Imaging and Spectral Methods, Session III: Metrology for LEDs, and Session IV: Advances in Radiometry.
