TAU-0035-00-10, version 100 April 2009 1-1
1 Introduction
The Tau is a long-wavelength (8 – 14 microns) uncooled microbolometer camera designed for
infrared imaging applications that demand absolute minimum size, weight, and power
consumption. It is available with multiple different lens focal length options, as well as a No Lens
option intended for customers who mount their own lens and perform ancillary Alternate Lens
Calibration—See “Software accessory SDK for Windows & Embedded” on page 2-3.

The camera provides “power-in, video-out” capability, which means that one need only apply input
voltage to receive analog video. For those applications demanding more advanced control, the
Tau camera includes a serial interface (RS-232) for transmitting camera commands and
receiving status. In more demanding situations, the Tau camera also provides 14-bit and 8-bit
digital video options, including CMOS, BT-656, and the Legacy Photon LVDS—See “Tau Digital
Data Channel” on page 4-1.
