The luminous flux is the quantity to represent the optical power that is perceived as light by the human eye, and its scale, lumen is one of the most important photometric quantities. Accurate luminous flux calibration is crucial in many scientific and industrial fields, for example, for quality systems in manufacturing light sources or for reliable evaluation of newly developing light sources such as LEDs and OLEDs. A new goniophotometer system for absolute calibration of total luminous flux has been developed at AIST. The new goniophotometer has the long photometric distance (2.7 m) to minimize the uncertainty due to the lamp alignment. The goniophotometer is calibrated against the illuminance responsivity scale directly traceable to the AIST high-accuracy cryogenic radiometer. The new calibration facility based on the AIST goniophotometer has also been developed. AIST is now offering new calibration services for the total luminous flux of lamps according to Japan Calibration Service System (JCSS).
