    Tau™ 2

    LONGWAVE INFRARED THERMAL CAMERA CORE

    Made in USA, the Tau® 2 OEM thermal imaging cameras offer an unmatched combination of features and reliability, making them well-suited for demanding applications including unmanned vehicles, thermal sights, and handheld imagers. Improved electronics provide powerful image processing modes that dramatically improve detail and contrast through continuous histogram equalization. Radiometry is available in every pixel for both 640 × 512 and 336 × 256 resolutions and all three camera grade levels. All Tau 2 configurations share electrical, mechanical, and optical interfaces allowing integrations to be designed that work seamlessly with all formats. Available in Commercial, Performance, and Industrial variants, each with unique sensitivity and pixel operability thresholds to meet operational requirements. Radiometry is an optional feature for Performance-grade cameras, and standard feature with Industrial-grade. All Tau 2 configurations and resolutions share electrical, mechanical, and optical interfaces allowing integrations to be designed that work seamlessly with all formats.
