# LED Standands

NIST scientists Yuqin Zong (pictured) and Yoshi Ohno have developed a new method for measuring the optical properties of high power LEDs that will allow manufacturers to accurately obtain and compare data. By mounting the LED on a temperature controlled heat sink, the researchers can test the LEDs at their normal operating temperature (important to commercial manufacturers) at high speed (important to LED manufacturers).
