Ultra-fast 20GHz IR Detector

    Item Description

    This item is for purchase and shipment only in North America (USA, Canada, Mexico).  Please contact your local Hamamatsu office in other countries.

    This is a ultrafast mid-infrared photodetector with a response bandwidth of 20 GHz (-3 dB). It operates bias free with no cooling required, so no external power supplies are needed. Setup happens in two simple steps: connecting the SMA fitting to measuring instruments (oscilloscope etc.), and directing light incidence to the internal focusing lens. 


    • Ultra-fast MIR photodetector with over 20 GHz response
    • Response frequency range (-3 dB): DC to 20 GHz
    • Peak sensitive wavelength: 4.65 µm
    • Photosensitivity: 1 mA/W (Typ.)
    • No cooling, and no operation bias are required

    The module is a user‑friendly device, thus can be easily used in a variety of applications including heterodyne detection and high frequency/high time resolved measurement.
