Tau 2 336 LWIR Thermal Imaging Camera Core

Tau 2 is the latest generation product in FLIR’s Tau family of LWIR uncooled thermal imaging camera cores. Two significant advances in Tau 2 are the introduction of:

  • Enhanced electronics for improved image processing; and
  • FLIR’s 336×256, 17μ-pitch sensor format (in addition to the 324×256, 25μ-pitch & 640×512, 17μ-pitch Tau 2 versions)

Key capabilities available in the Tau 2.0 release include:

  • 30/60Hz NTSC (25/50Hz PAL) field-switchable frame rate support for the 324×256, 25µ-pitch and the 336×256, 17μ-pitch versions of Tau 2 cameras
  • Improved response 336×256, 17μ-pitch sensor enables higher magnification with existing Tau lenses
  • Single pixel symbol resolution for all Tau 2 configurations

There is no difference in form or fit between Tau 2 and the first generation Tau cameras. The upgraded Tau 2 electronics enable additional functions and capabilities that are planned for release on a periodic basis in 2012. Since the electronics are common between the Tau 2 – 640, Tau 2 – 336, and Tau 2 – 324, integrators have direct compatibility between the different camera formats, and most Tau camera versions share the same lens options. FLIR also offers a low-cost Tau 2 – 160 option for applications that do not require high resolution imaging.

Note:  Earlier versions of Tau cannot be upgraded to the newer Tau 2 configuration.

The International Traffic in Arms Regulations (ITAR) details the regulations governing the export of defense related materials and technologies. The U.S. Munitions List (USML) categorizes goods and technologies governed by the ITAR.
In June 2008 the U.S. government made a determination that thermal cameras exceeding a certain pixel count are USML classified under the ITAR. As a result, the Tau 640 and related technical data and information are controlled for export purposes to the ITAR. Tau 640 data provided at this web site has been approved for public release, and is not export-controlled. It is a violation of the ITAR to export or re-export the Tau640 or related technical data (other than data approved for public release) without first receiving authorization to do so from the U.S. Department of State. This restriction does not apply to the “slow video” versions of Tau 640 that operate at frame rates of less than 9Hz.
Due to the Tau 640’s export status, any purchase, receipt, and/or use of any Tau 640 camera or technical data (other than data approved for public release) is contingent upon an agreement to abide by all export laws and regulations of the United States, including, without limitation, the ITAR. Further, it must be acknowledged that export or re-export of the Tau 640 or related technical data (other than data approved for public release) is not allowed without the requisite authorization from the Directorate of Defense Trade Controls of the Department of State.
In addition, § 122.1 of the ITAR states that “any person in the U.S. who engages in the business of either manufacturing or exporting defense articles or furnishing defense services is required to be registered with the Directorate of Defense Trade Controls (DDTC).” It is the responsibility of any organization that buys, receives, and/or uses a Tau 640 to register with DDTC in such cases.
Violations of the ITAR are extremely serious and can result in fines, debarment, and criminal sanctions. Please direct any questions or concerns regarding the export status of the Tau 640 to Krista Larsen, FLIR’s Director, Export Compliance Traffic, at (503) 498-3316.
Again, ITAR compliance for the Tau 640 applies to the full-rate (30Hz & 25Hz) versions of the camera, and does NOT apply to the “slow video” versions that operate at frame rates of less than 9Hz.
