The Jaz™ Modular Measuring Suite from Ocean Optics, Dunedin, FL, is now available for radiometric analysis of LEDs, flat panel displays, lamps, and other radiant sources. The Jaz Light Meter is a pre-configured, pre-calibrated spectrometer suite that is ideal for quality control, lab and field measurements of LED chips, assemblies, and other luminaires. Spectral characteristics can be measured, and key parameters like Lux, Lumen, PAR, and Watt values can be calculated. The battery module enables measurement for up to 8 hours, without recharging, and Jaz’s SD card slot offers a convenient way to store spectral data. Jaz’s data can be downloaded into SpectraSuite for post-processing and determining CIE color coordinates, color rendering indexes, and color temperature.
