Source Imaging Goniometer® SIG-400
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 PM-1600F Series Imaging Colorimeter or Photometer 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'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. A complete turnkey system for generating accurate input for optical design The SIG-400 system consists of a ProMetric® Imaging Colorimeter, a goniometric assembly for positioning the imaging colorimeter and the light source relative to each other, and SIG 2.0 control and analysis software. 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. These measurements are aggregated into a Radiant Source Model™ (RSM) format, which is a detailed, industry-standard model for light source near-field data representation. RSMs contain all of the measurement information, including the image data, so the measurement results can be reviewed in detail at any time. RSMs are used to compare the optical properties and design of various LEDs and to generate input to optical design software for use in luminaire and optical system design. Applying Radiant's ProSource® Software to the RSM, 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. Because the RSM is a complete description of the light source, it can be used to generate and regenerate ray sets at will - smaller numbers of rays for rough design and a large number of rays for final design - making the overall design process more efficient.
