Teledyne FLIR Releases Tau® 2+ Longwave Infrared Thermal Camera Module with Enhanced Performance and Increased Sensitivity

Teledyne FLIR, part of Teledyne Technologies Incorporated (NYSE:TDY), today announced the Tau 2+, the highest sensitivity longwave infrared (LWIR) Tau 2 camera from Teledyne FLIR. With the same reliable and widely deployed, real-world-tested Tau 2 mechanical, electrical, and optical interfaces, the Tau 2+ is a drop-in replacement, but with a 1.5 times sensitivity improvement and an entirely redesigned image processing engine to deliver dramatically enhanced sharpness and contrast.

“The Tau 2+ is the go-to thermal camera module for the most challenging environments, especially when detection of the smallest, hardest to find targets over long distances is required,” said Dan Walker, VP Product Management OEM Cores, Teledyne FLIR. “Improved LWIR thermal performance and market-leading reliability still make it the lowest-risk, ideal thermal module for unmanned vehicles, security applications, and thermal sights.”


Object Detection at Greater Distances

With a noise equivalent differential temperature (NEDT) of less than 25 mK (milliKelvin) – half the typical industry standard – the Tau 2+ offers significantly improved detection, recognition, and identification (DRI) performance. And with Tau’s existing wide lens options and simple optical interface for integrator-designed optics, this improved DRI can now be exploited over multiple fields-of-view (FOV).


Resolve Key Information

The Tau 2+ has a best-in-class image processing algorithm providing clearer thermal details in challenging environments. Featuring a new level of minimum resolvable temperature differences (MRTD), improved scene contrast with blacker blacks and whiter whites, and a low image noise. Tau 2+ is fit to resolve key information with improved contrast and sharper images.


Designed for Integrators

The shared Tau 2 interface and access to a highly qualified US-based Technical Services team for integration support reduces development risk and shortens time to market. Truly designed for integrators, the Tau 2+ has the industry’s widest variety of lens options available and comprehensive product documentation with many years of reliable Tau production experience. Commercial off-the-shelf connectors include USB, CMOS, Camera Link, or Ethernet.

The Teledyne FLIR Tau 2+ is available for purchase globally from Teledyne FLIR and its authorized dealers. To learn more, visit
