SETI’s UV LEDs Complete Space Qualification

Facebook X LinkedIn Email
COLUMBIA, SC, Nov. 29, 2010 — Sensor Electronic Technology Inc. (SETI), together with Stanford University and National Security Technologies of Livermore, Calif., has demonstrated extreme environmental robustness and radiation hardness of its UVTOP deep ultraviolet LEDs. Deep UV LEDs with peak emission wavelength of 255 nm have passed stringent space qualifications for large temperature variations and mechanical shocks with 27 cycles of 100K temperature cycles and 14g rms random mechanical vibrations. The forward voltage, emission spectra, and optical output power exhibited no significant changes after these harsh...Read full article
