Garm LW Pol

The world’s first commercially available cooled LWIR polarimetric detector, the Garm LW Pol 320x256 array with 30 µm pixel pitch combines both extreme infrared sensitivity and polarization angle measurement capability. Extended functionality and brand new emerging applications are at reach.


The Garm LW Pol has a built-in 2x2 pixel array structure. With each pixel sensitive to a distinct polarization angle (0°, 45°, 90°, and -45°), it can sense the smallest polarimetric information within any scene without optical parallax or frame rate constraints. This unique detector allows real-time capture of polarimetric video and images with high polarimetric contrast and freedom from filter induced transmission losses.


  • Efficient oil spill detection
  • Camouflage denial
  • Improvised Explosive Device (IED) detection
  • Human infrared face recognition
  • Industrial applications (thermography, NDT…)
  • And much more
