XUV UV VUV Soft X-Ray Photodiode Detectors



 

International Radiation Detectors (IRD), Torrance, CA, was formed in July 1991 to manufacture absolute devices for measurement of visible, UV, XUV, EUV and soft x-ray photons. The primary activity of IRD is to design, manufacture and sell semiconductor radiation sensors to detect photons and other particles.

One hundred percent internal carrier collection efficiency silicon photodiodes have been developed and commercialized by obtaining funds through Small Business Innovation Research (SBIR) grants/contracts from U.S. Department of Commerce, Department of Energy and National Institute of Health. Presently, IRD is the only company in the world manufacturing and marketing stable silicon photodiodes for detection of vacuum ultraviolet and extreme ultraviolet photons.

Due to the unparalleled quantum efficiency stability and radiation hardness of IRD photodiodes, they have been successfully used in European SOHO and Coronas-Photon, American SNOE, SORCE, GOES, TIMED and EOS solar space instrumentation. IRD is the only NIST approved vendor for silicon photodiode transfer standards in 5 nm to 250 nm spectral region.
