Imaging Sphere – Luminous Intensity (IS-LI)

High speed, low cost, luminous intensity measurement system for LEDs and other small sources.

Radiant Imaging’s new Imaging Sphere™ (IS-LI) is the first system to enable rapid, comprehensive measurement of luminous intensity, radiant intensity, CIE chromaticity coordinates and correlated color temperature (CCT), all as a function of angle, for LEDs and other small light sources. Based on patented technology developed jointly with Royal Philips Electronics, the IS-LI acquires data over an entire 2 ?? steradian in a single measurement, taking just seconds or less. Previously, obtaining these precision measurements required goniometric tools; but, with no moving parts, the new IS-LI is orders of magnitude faster than traditional methods. This unique combination of high precision, high resolution and speed enables real-time, production-line QC of LEDs for the first time, and makes the IS-LI ideal for R&D purposes as well. The IS-LI system consists of a 20" (550 mm) diameter, hemispherical measurement chamber, mated with our PM-1400 Series Imaging Colorimeter (with a 512x512 pixel detector). Other imagers offering different dynamic range and resolution are available as well. System software supports automated and/or customized measurements, as well as data analysis and display functions. Data can be displayed as isometric plots, cross-sectional graphs, radar plots, bit maps and color graphs.
