The Arc A635P LRF combines an extremely sensitive 640×512, 12µm, <20mK NETD thermal sensor and a powerful 35mm f1.0 objective lens, achieving a generous 21.9×17.6m @ 100m FOV, unprecedented thermal clarity, and a detection range of up to 1800m.  The sensor’s 20mK NETD thermal sensitivity achieves richly detailed and vivid thermal imagery, capturing each and every anatomical detail of even the smallest observed heat source, elevating your observation experience regardless of conditions. Pixfra’s intuitive PIPS (Pixfra Image Processing System) 2.0 achieves thermal imagery that is always crisp and clear by minimising environmental noise, boosting contrast, and enhancing image clarity and detail..
