FLIR Boson® - 9.2mm Short Lens
Compact LWIR Thermal Camera
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 with the short lens only comes as 640 x 512 resolution.
The FLIR Boson 9.2mm with short lens weighs 34.7 grams. The camera measures (LxWxH) 41.16 x 29 x 34.5mm including the lens.
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.

DRAMATIC REDUCTION IN SIZE, WEIGHT AND POWER (SWaP) WITH NO REDUCTION IN PERFORMANCE
A full-featured VGA thermal camera module at less than 4.9 cm3.
- 21 x 21 x 11 mm camera body and weight as low as 7.5 g.
- Low power consumption, starting at 500 mW
- 12 µm pixel pitch VOx microbolometer with 320 and 640 resolutions.
- Rugged construction and highest temperature rating -40°C to 80°C.
