Teledyne FLIR, part of Teledyne Technologies, announced the Tau 2+, the highest sensitivity long-wave infrared (LWIR) Tau 2 camera from Teledyne FLIR. With the same 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, in a company statement.

“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.”

With a noise equivalent differential temperature (NEDT) of less than 25 mK (milliKelvin), the Tau 2+, offers 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.)


The Tau 2+, has an image processing algorithm that provides 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. Tau2+ is fit to resolve key information with improved contrast and sharper images.

The shared Tau 2 interface and access to a 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.
