Opto Diode's semiconductor radiation sensors for detecting photons and other particles includes the AXUV 100G Absolute X-ray Photodiode. The X-ray detector possesses known active silicon thicknesses and 100 percent internal quantum efficiency, making possible absolute measurement of X-ray flux with energies 100 keV and beyond. X-ray responsivity measurements performed at PTB Germany confirm the responsivity of AXUV 100G devices can be calculated from their known silicon thickness. Opto Diode’s unique IRD line of AXUV 100G photodiodes features a large (10 mm x 10 mm square) active area with room-temperature operation and a small detector.
