Description

Precise measurement of near-field luminous intensity specifically for LEDs and other small light sources

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 Series Imaging Colorimeter to generate highly accurate near-field models for LEDs; this data can be used directly to investigate the performance of the LED or it can be exported, via Radiant Vision Systems's ProSource® Software, for use in all major optical design software packages.

Efficiency and cost savings by focusing on LED measurement needs.

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 captures images of the light source from multiple angles, building a 3-dimensional spatial image of the color and luminance output of the device. Applying Radiant's ProSource Software, ray sets containing an arbitrary number of rays can be generated for export to other optical and illumination system design software packages such as ASAP, FRED, LightTools, LucidShape, Opticad, OSLO, SimuLux, SPEOS, TracePro, and Zemax, as well as general file formats.
