Compact LWIR Thermal Camera Core
The Boson® longwave infrared (LWIR) thermal camera module sets the standard for size, weight, power, and performance (SWaP). Utilizing FLIR’s advanced image processing and several industry-standard communication interfaces, Boson enables applications from firefighting to unmanned aerial vehicles and automotive development kits, all for as little as 800mW. The 12 µm pitch Vanadium Oxide (VOx) uncooled detector comes in two resolutions – 640 × 512 or 320 × 256. Both resolutions are available with multiple lens configurations, adding flexibility to integration programs. Radiometric models are also available with absolute temperature measurement in select configurations.
