Measuring LED Power and Irradiance with Calibrated Photodiodes

By Dr. Efi Rotem
17 March 2015

White Paper Lead ImageIn many industries, LEDs are replacing traditional broadband light sources, such as mercury, deuterium, Xenon and quartz-halogen lamps. Systems and applications transitioning to LEDs are reengineered in terms of optics, electronics, heat management, and more. Similarly, the equipment used by professionals to measure the output of these sources needs to be fitted for measuring LEDs.
