Study of Different Testing Methods Used in UV-LED Optical Measurement

In this study, three different partial radiant flux testing methods including the large-area silicon (Si) photodiode method, the assembling Si photodiodes box method, and the integrating sphere method were used to measure the optical power of UV-LED die. The optical simulations and the experiments have been performed to study the influence of the varying LED die position and tilt angle. The optica...
