PM-NFMS™ Near-Field Measurement System for Large Light Source Performance Characterization

The PM-NFMS™ system performs brightness and color measurements as a function of viewing angle for large light sources. It provides accurate nearfield luminance distribution data for developers of large light sources, for automotive, transportation, architectural, and other applications. Because the PM-NFMS™ system 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 spotmeterbased measurements.
