    Cardinal 640 Low Noise (LOON)

    This FPA consists of a Digital Low Noise ROIC and state-of-the-art Planar InGaAs P-I-N diode array. The detector can be supplied in two types of package:

    • Metallic package which includes a Thermo-Electric Cooler (TEC)
    • Ceramic TEC-less package

     

    The metallic package can be supplied with a low power proximity board which provides:

    • Timing and sensitive power supply to the ROIC
    • Camera Link Interface (similar to the Cardinal 640)
    • TEC control electronics
