Tau® 2+

Longwave Infrared Thermal Camera Module
with Enhanced Performance and Increased Sensitivity

Tau 2+
Made in USA, the Tau 2+ is the most advanced, highest performance longwave infrared (LWIR) Tau 2 camera model from Teledyne FLIR. It maintains the widely deployed and real-world-tested Tau 2 mechanical, electrical, and optical interfaces allowing plug-and- play with existing designs. Its new 1.5x sensitivity improvement and an entirely redesigned image processing engine deliver dramatically enhanced scene contrast and sharpness. Tau 2+ is the go-to thermal camera module for the most challenging environments, including detection of the smallest, hardest to find targets over long distances. Enhanced LWIR thermal performance and market-leading reliability provide low-risk development in the short run and the long run, making it the ideal thermal camera module for unmanned vehicles, security applications, and thermal sights.
