OSRAM Opto Semiconductors presents Radiometry and Photometry as part of the LED Fundamentals series. In this presentation we look at Radiometry, the detection and measurement of radiation across the full electromagnetic spectrum, including ultraviolet, visible and infrared radiation. Photometry is concerned only with the visible portion of the spectrum, from about 380 to 780 nanometers.
