InGaAs 640x512

Cardinal 640 Loon (Low Noise)

InGaAs SWIR 640 x 512, 15µm, digital

Description Typical Performance Applications Configurations Downloads

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
