FLIR’s Tau 640 is a 640×512 LWIR uncooled focal plane array (FPA) camera with a pixel size of 17 microns.
Our Tau2 cores are slow video cores, this exempts the camera from export license requirements. The slow video rate is 7.5 fps for NTSC and 8.3 fps for PAL.
A number of optional accessories provide additional Tau connectivity, including a Photon replicator board that enables backward compatibility with Photon accessories, and a VPC (video/ power/ communications) expansion board that features power & communication over USB.
This product is intended for use by INCORPORATION INTO ANOTHER PRODUCT ONLY and is not considered by FLIR to be a finished end-product fit for general consumer use.
Some key features of the Tau 640 camera are listed below.
- Field switchable between NTSC and PAL video formats
- CMOS and BT.656 digital video options, as well as the legacy Photon LVDS
- High-speed serial camera communication up to 921,600 baud (via the Tau VPC serial-to-USB Accessory)
- Advanced, user-friendly interface for camera control and configuration
- On-board image capture and storage
- Camera power and communication over USB option (via the Tau VPC serial-to-USB Accessory)
- EMI suppression to Class B with rear cover installed, and Class A without rear cover
- Up to 200g shock tolerance
- Discrete camera control functions available to OEMs
- Multiple lens options available in wide and narrow fields of view
- Wide field of view lenses sealed to IP-67
- Threaded WFOV lens barrel for bulkhead mounting or external attachment options
- Field upgradable software/firmware
- Support for user-defined symbology
- Supplemental FFC software feature allows OEMs to calibrate out lens effects to improve image quality
- Customers can load their own start-up splash screen (minimum purchase required)
The Tau 640 has several lens options. See the Options tab above for detailed lens information.

IMPORTANT EXPORT INFORMATION
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.
