Tau™ 2

Model: Tau 640

LONGWAVE INFRARED THERMAL CAMERA CORE

Tau® 2 thermal imaging cameras offer an unmatched set of features, making them well-suited for demanding applications like Unmanned Airborne Vehicles (UAVs), thermal sights, and handheld imagers. Improved electronics provide powerful image processing modes that dramatically improve detail and contrast. Its options include full radiometry, increased sensitivity (<30mK), and 640/60Hz frame rates. Since the Tau 2 640 and 336 configurations share electrical functions, common integrations can be designed that work seamlessly with both formats.


Loaded with Features; Ready for More

LOADED WITH FEATURES; READY FOR MORE

Advanced electronics and image processing give Tau an unprecedented feature set, and make it ready for your next big idea.

 

 

Improved Image Processing

POWERFUL IMAGING PROVIDES EXPANDED CAPABILITY

Tau 2’s expanded capability ensures accurate temperature measurement for radiometry, analytics and telemetry.

 

 

Histogram Equalization - HEQ

INFORMATION-BASED HISTOGRAM EQUALIZATION (HEQ)

HEQ automatically adjusts image contrast to let you see what matters most in a scene, and give you the image detail that makes a difference.
