NEAR-FIELD GONIOPHOTOMETRY SUPPORTS THE DEVELOPMENT OF ENERGY EFFICIENT LUMINAIRES AND SOLID STATE LIGHTING

By Robert Yeo, Pro-Lite Technology

The measurement of luminaires has traditionally been performed with a photometer placed in the far-field, which measures the illuminance from the light source one angle at a time. A near-field goniophotometer exploits the latest advances in imaging photometry and represents a more affordable and flexible option compared with a far-field instrument
