Ultraviolet Diodes

altOpto Diode (Newbury Park, CA) now offers the IRD SXUV 100 Ultraviolet/Extreme Ultraviolet (UV/EUV) Photodiodes. The advanced photon detectors feature very high radiation hardness and are designed for long-lifetime operation in high particle flux environments with no loss of responsivity. The IRD SXUV 100 photodiodes have a 10 mm x 10 mm square active area (100 mm≤). The nitrided metal silicide front window of the diode permits operation without loss of performance in high humidity and other environmental conditions that normally require sealed packages. Diodes with single active areas are available from 1 to 576 mm≤; quadrant diodes with several central openings may also be specified. Tested to rigorous standards, the IRD SXUV 100 photodiode revealed no observable responsivity loss after exposure to billions of 157 and 193 nm pulses and exposure to 8 W/cm2 of CW 248 nm laser irradiance for three weeks.
