FLIR TAU 640 100MM
• 640x480 Thermal Imaging Camera Core • 6.2°(H) × 5°(V) FOV
The Flir Tau 640 100mm is an incredibly small thermal imaging camera with 17-micron pixel pitch, and VGA resolution
The Flir Tau 640 100mm (41640013H-FPNLX)combines compact size, very low power requirements, and outstanding imaging performance, making it the ideal thermal camera core for a variety of applications.
The FLIR Tau 640 thermal camera core has been specially designed for Original Equipment Manufacturers (OEM) and allows you to use the thermal camera core with many different lenses. It can be easily integrated into systems that require an advanced, uncooled thermal imaging solution.
The FLIR Tau 2.6 in" camera body volume is possible through a combination of FLIR's 17-micron pixel focal plane array, as well as an advanced shutter design that fits within the 1.5 in" camera cross-section. Since the electronics are common between the FLIR Tau 320 and FLIR Tau 640, integrators have immediate, direct compatibility between cameras, and both Tau camera versions share several lens designs.
FLIR Tau 640 is the first uncooled thermal camera core to combine many versatile attributes into one affordable, high-performance package. Many common controls of the thermal camera cores are brought out via the FLIR Tau GUI (graphical user interface).

FLIR Tau 640 Applications
The FLIR Tau 640 thermal camera core is ideal for thermal imagers, unmanned vehicle payload cameras, firefighting instruments, and thermal sights. FLIR Tau is the best thermal camera core for applications that demand a unique combination of light weight, small size, and low power consumption.

User configurability
The Tau 640 offers complete configuration and integration flexibility with the powerful Tau GUI and optional SDK. Through our XP bus interface, users can:
- Select the optimal digital data interface – 8/14-bit serial LVDS, 8/14-bit parallel CMOS, and BT.656 (now an input into many LCDs)
- Convert the digital output of Tau to Camera Link format data
-
Directly command the camera through configurable discrete inputs to control digital zoom, polarity, etc. (up to eight commands selectable*)
*Use of CMOS interface limits users to one discrete function
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. Persons handling the product(s) must have electronics training and observe good engineering practice standards. As such, this product does not fall within the scope of the European Union directives regarding electromagnetic compatibility.
Exporting the FLIR Tau 640 from the United States
The FLIR Tau 640 cameras operate at a 30 Hz (25 Hz PAL) frame rate. For cameras that will be exported or re-exported outside of the United States, we offer a "slow video" option that exempts the camera from export license requirements. The slow video frame rates are 7.5 Hz for NTSC and 8.3 Hz for PAL. Digital video is generated at 8- or 14-bit resolution at the equivalent analog video frame rate of the camera.

FLIR Tau 640 Export Video Demo
These and all thermal imaging cameras are export controlled devices. Due to U.S. export regulations there are restrictions for export.
Unless export licensing is applied for and granted 30Hz units can not be exported. After applying for an export license it can take quite a few months to more than a year for the license to be granted if granted at all. If the export license is granted government fees are incurred and need to be paid by the consignee prior to shipping. 7.5Hz versions can be exported without an export license but only to select countries, customers and end users.
Several FLIR Tau-specific accessories are available:
- VPC (video/ power/ communication) breakout module (FLIR p/n: 421-0039-00)
- A tripod adapter (FLIR p/n: 261-2071-00)
- The Photon Replicator Board (FLIR p/n: 421-0040-40) give users backward compatibility with the Photon Accessory Kit (FLIR p/n: 421-0021-00)
- The Camera Link Expansion Board (FLIR p/n: 421-0046-00) furnishes 14-bit digital data. A separate MCX connector is provided for analog video. Input power and camera communication are enabled via the mini-USB port.†
- The Tau Lens Focus Tool (FLIR p/n: 421-0037-00) lets users adjust the focus of 13 mm and 19 mm lenses
- The Tau Lens Locking Ring (FLIR p/n: 421-0041-00) lets users mount select Tau 640 cameras to a bulkhead
- The software SDK (FLIR p/n: 110-0133-16)
