Sphere measures LED intensity

Nov. 2, 2006
IS-LI enables rapid, comprehensive measurement of the luminous intensity of LEDs and other small light sources. Based on patented integrating-sphere technology, the IS-LI acquires luminous-intensity data over an entire 2p steradian in a single measurement in seconds or less. The system delivers up to 16-bit luminance measurements, with an angular resolution of 1% or better.

The system delivers up to 16-bit luminance measurements, with an angular resolution of 1% or better. Alternately, the IS LI can analyze color versus emission angle. The IS-LI consists of a 20-in.-diameter, hemispherical measurement chamber mated with a CCD-based imaging photometer or colorimeter. Data can be displayed as isometric plots, cross-sectional graphs, radar plots, bit maps, and color graphs.
