FLIR’s Tau: a low-cost, high volume longwave
thermal camera core A fusion of small size, light weight, miniscule power consumption, and outstanding imaging performance
makes Tau the ideal thermal camera core for many demanding applications.
From handheld thermal imagers to unmanned vehicle payload cameras, from firefighting instruments to
thermal sights, Tau is the best choice for applications that demand a unique combination of light weight,
small size, and low power.
Tau is the first uncooled thermal camera core to combine all of these attributes into one affordable,
high-performance package.

The Camera Link XP accessory provides access to Tau digital data only.
Portions of the base Camera Link specifications are not met:
• C amera control and power are not supported via the Camera Link
connector (the XP accessory does furnish a mini-USB port for
power and communication)
• External frame sync is not supported.
User Configurability
The Tau offers complete configuration and integration flexibility with the
powerful Tau GUI. An optional SDK provides access to the complete set of
commands available for the Tau camera.
Through our new XP bus interface, users can:
•Directly command the camera through configurable discrete inputs for such
control as zoom, polarity, frame/video capture, etc. (up to eight commands
selectable).
•Select composite video type – NTSC or PAL.
•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).
•Field-upgradeable to the latest versions of camera software and firmware.

Tau Lens Data
Tau cameras have nine lens choices available, giving integrators flexibility in designing installations. The four wide field of view lenses (5, 9, 13, and 19 mm) are
integrated directly into the Tau’s camera body for improved durability and performance. These lenses are sealed, meet IP-67, and have a hard carbon-like coating
for long life. All Tau lenses are factory-focused to infinity with a collimator.
