- 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.
- The SIG-400 is Radiant's fourth generation of the Source Imaging Goniometer and the realization of over 15 years of experience in light source measurement. 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.
