RADIANT VISION SYSTEMS PM-NFMS™

Illuminance and Luminance Characterization For Large Light Sources

ProMetric® Near-Field Measurement System is built and designed to characterize luminance distribution data for developers of large light sources for automotive, transportation, architectural and many other applications. 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.

Radiant Visiton Systems PM-NFMS consists of a ProMetric Imaging Colorimeter, a two-axis goniometer for precisely adjusting the display’s angular position relative to the imaging colorimeter, and PM-NFMS software that controls both the imaging colorimeter and the goniometer during the measurement sequence. The PM-NFMS software also includes a comprehensive set of data analysis tools. PM-NFMS can output IES format files, EULUMDAT files, illuminance distribution on a plane as table, and Radiant Source Model™ (RSM) files. RSM files can be used to generate either photopic, colorimetric, or spectral ray sets for use in optical design tools by using ProSource® Software. Learn more
