More and more incandescent lights are being replaced by LEDs each day. LEDs have the advantages of increased efficiency, color specificity, size, response time, lifetime, and numerous other factors. StellarNet's line of low cost miniature radiometers are the perfect tool to analyze LEDs for both irradiant output, color, spectral profiling, and a handful of other useful values. These instruments are NIST calibrated to measure the absolute intensity over the wavelength range in nanometers provided by the selected spectrometer model. Currently, StellarNet offers LED Radiometer systems in the 200-1700nm range; the table at the bottom of the page outlines various ranges for each StellarNet Spectroradiometer. The StellarNet EPP2000 standard model, BLUE and GREEN-Wave, EPP2000C concave grating model, and the EPP2000-NIR InGaAs model can all be configured for perfect LED measurements. For a complete LED measurement system, in addition to a StellarNet Spectrometer, a fiber optic cable and an integration sphere are needed for both accurate and precise measurement.
