FLIR Compact LWIR Thermal Camera Core: Boson®

The Boson® longwave infrared (LWIR) thermal camera module sets a new standard for size, weight, power, and performance (SWaP).  It utilizes FLIR infrared video processing architecture to enable advanced image processing and several industry-standard communication interfaces while keeping power consumption low.  The 12 µm pitch Vanadium Oxide (VOx) uncooled detector comes in two resolutions — 640 x 512 or 320 x 256. It is available with multiple lens configurations adding flexibility to integration programs.

With a weight as low as 7.5g and a camera body of only 21 x 21 x 11mm (0.83 x 0.83 x 0.43 in) without lens or 640-model shutter, the Boson represents an industry-leading reduction in SWaP with no reduction in performance. Advanced embedded processing and video analytics, as well as software-customizable functionality, give this small camera big capabilities, including integration with auxiliary sensors such as third-party cameras, GPS, and IMU.
