04 Nov 2011 Opto Diode (www.optodiode.com), a division of ITW, and a member of the ITW Photonics Group, offers semiconductor radiation sensors for detecting photons and other particles. With the recent acquisition of International Radiation Detectors (IRD), the company’s new product line includes 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 mm²). 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 mm²; 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.
Opto Diode’s advanced sensor technology devices feature unparalleled quantum efficiency stability and have been successfully used in both European SOHO and Coronas-Photon projects and in American SNOE, SORCE, GOES, TIMED and EOS solar space instrumentation. Ideal for applications that require extreme stability for the detection of vacuum ultraviolet and extreme ultraviolet photons, the IRD SXUV 100 silicon photodiodes are in-stock and are available now.
