Imaging Goniometers

Radiant Vision Systems fully-automated goniometric systems are combined with a ProMetric® Imaging Colorimeter or Photometer and specialized software to capture a precise, comprehensive model of a light source’s near-field output.

Imaging Goniometers

PM-NFMS (ProMetric Near-Field Measurement System) measures brightness, color, and, optionally, spectrum as a function of viewing angle for large light sources. It is designed to provide accurate luminance distribution data for developers of large light sources for automotive, transportation, architectural, and other applications. Because the PM-NFMS captures a complete near-field model of the light source, it provides much more comprehensive information – in a much smaller measurement space – than can be obtained from traditional spot meter-based measurements.

The Radiant Vision Systems Source Imaging Goniometer® (SIG) systems are fully automated, computer-controlled goniometric systems that use a PM03/PM13 ProMetric Imaging Colorimeter or Photometer to capture a precise model of a light source's near-field output. The image data and the Radiant Source Model™ (RSM) generated from it provide a complete and precise characterization of the light source output that can be used for design evaluation and imported into any major optical design package to allow accurate design of lighting systems.
