The SIG-400 (Source Imaging Goniometer®, Gen. 4) is a fully-automated, computer-controlled goniometric system designed specifically to meet the needs of LED researchers, developers, manufacturers, and users for LED die and device characterization. The SIG-400 uses a ProMetric® I Imaging Colorimeter to generate highly-accurate near-field models of LEDs. This data can be used directly to investigate the performance of the LED, or it can be exported using Radiant Vision Systems ProSource® Software, for use in all major optical design software packages. By combining Radiant's latest advances in imaging colorimetry, robust mechanical design (to provide absolute accuracy), and easy-to-use control software, the SIG-400 can be readily applied to a broad range of measurement applications. By focusing on the needs of LED measurement, the SIG-400 is also very cost-effective. The SIG-400 captures and aggregates images and flux measurements from thousands of angular viewpoints around a light source to precisely characterize the source's near-field output. The SIG-400 supports measurement of vertically-oriented light sources and can be ordered with both microscope and extended field-of-view optics, thus providing the flexibility to measure both LEDs and other light sources. The SIG-400 system consists of a ProMetric® Imaging Colorimeter, a goniometric assembly for positioning the imaging colorimeter and the light source relative to one another, and SIG Control and Analysis Software.
