RADIANT VISION SYSTEMS SOURCE IMAGING GONIOMETER

Precise Measurement Of Near-Field Luminous Intensity Small Light Source

Radiant Vision Systems SIG-400 is built and designed specifically for LEDs and small light source by capturing image data describing the spatial structure of the luminance and chromaticity of the light source from multiple viewing angles. 

The SIG-400 is Radiants 4th generation Source Imaging Goniometer. SIG-400 can be applied to a broad range of measurement applications by merging our latest advances in imaging colorimetry, robust mechanical design, industry-leading accuracy, and easy-to-use control software. It provides a cost-effective solution by focusing on the needs of LED measurement applications.

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 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 light source. These measurements are aggregated into a Radiant Source Model™ (RSM) format, which is a detailed, industry-standard model for representing a light source’s near-field data. RSMs are used to compare the optical properties and designs of various LEDs and to generate input to the most common optical design software packages for use in luminaire and optical system design.
