Ophir Photonics showcased “FluxGage”, a compact, all-in-one LED luminaire measurement system which measures flux, color, and flicker, important quantities for evaluating the performance of LED-based products. The measurement system is three times as small as an equivalent integrating sphere. A spectrometer has been incorporated for color measurement of the spectrum, CCT, CRI, Duv, and chromaticity. There is also a fast photo detector for flicker measurements. No fibers are needed. It can measure luminaires of up to 610 by 450 mm.
