Tau 2 LWIR Thermal Imaging Camera Cores

FLIR Tau 2 thermal imaging cameras offer an unmatched set of features, making them well-suited for demanding applications like Unmanned Airborne Vehicles (UAVs), thermal weapon sights, and handheld imagers. Improved electronics now give Tau 2 even more capabilities, including radiometry, increased sensitivity (<30mK), 640/60Hz frame rates, and powerful image processing modes that dramatically improve detail and contrast. Since the electrical function are common between the Tau 2 640, 336 and 324, integrators have direct compatibility between the different camera formats, and Tau camera versions share many of the same lens options.

New features:

  • 2nd generation Digital Detail Enhancement™
  • Active Contrast Enhancement™
  • Smart Scene Optimization™
  • Information Based HEQ™ that automatically adjusts AGC
  • Silent Shutterless NUC™
  • Accurate temperature measurement for radiometry, analytics and telemetry

There is no difference in form or fit between Tau 2 and the first generation Tau cameras. The upgraded Tau 2 electronics enable additional functions and capabilities that are planned for release on a periodic basis. A comparison of the flir thermal imagers can be found here: Thermal Core Feature Comparison. Note that earlier versions of Tau (1.X) cannot be upgraded to the newer Tau 2 configuration.
