Tau 640 LWIR FPA Camera from FLIR Systems

The New Tau 640 camera from FLIR Systems is an LWIR focal plane array (FPA) camera that offers 17 µm of pixel size. The 640 x 480 camera has the ability to deliver NTSC video at a speed of 30 frames per second (fps) and PAL video at 25 fps. The thermal imager core provides field switching between both the video formats.

The uncooled FPA camera also has a ‘slow video’ option that delivers NTSC format at 7.5 fps and PAL format at 8.3 fps. This option relieves the camera of the need for export license. The LWIR camera is available with optional accessories that offer additional connectivity such as a VPC (video/power/communications) breakout module and a photon replicator board. The VPC module offers power and communication through USB, while the photon replicator renders the camera backward compatible with other photon accessories.
