Newbury Park, Calif., Oct. 26, 2011 — Opto Diode Corp., 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 (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 100 mm2 active area. The nitrided metal silicide front window of the diodes 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 also may be specified.

Tested to rigorous standards, the photodiodes revealed no observable responsivity loss after exposure to billions of 157- and 193-nm pulses and to 8 W/cm2 of continuous-wave 248-nm laser irradiance for three weeks.

The company’s advanced sensor technology devices feature high quantum efficiency stability and have been successfully used in solar space instrumentation.
