Defender 360LRF NETD ≤20 mK thermal imaging weapon sight is a flagship long-range thermal targeting system with variable optics and an integrated laser rangefinder. The device is designed for precise engagement of targets at medium, long and extended distances in demanding combat and tactical environments.
The system is built around a 384×288 VOx microbolometer sensor with a 12 μm pixel pitch and thermal sensitivity of NETD ≤20 mK @300K, ensuring stable target detection and confident recognition under minimal thermal contrast conditions, including night operations, fog, rain, smoke and complex thermal backgrounds.
Variable optical magnification from 1.8× to 5.5× combined with smooth and fast digital zoom from 1.0× to 4.0× allows rapid adaptation to different engagement distances. Dual fields of view of 13.1°×9.8° and 4.4°×3.3°, together with a variable 20/60 mm objective lens, provide flexibility between wide-area scanning and precise long-range targeting.
The integrated laser rangefinder with a range of up to 1200 meters, combined with a ballistic calculator, AI rangefinder, gyroscope, CSFBC system and GEO dot, forms a complete digital fire control solution.
🫡 We are a team of veterans
We are a team of veterans selecting thermal weapon sights based on real combat experience. Defender 360LRF NETD ≤20 mK was evaluated in terms of variable optics stability, laser rangefinder accuracy, ballistic calculation correctness, resistance to recoil up to 10,000 J, durability of the aluminum alloy housing and operational reliability during prolonged field deployments.

💬 Comment
Defender 360LRF NETD ≤20 mK is designed for scenarios where maximum detection range, fast engagement preparation and system autonomy are critical. The integrated laser rangefinder significantly reduces ranging errors, while the full set of sensors and ballistic tools allows rapid transition from detection to precise target engagement. Recoil resistance up to 10,000 J makes the system suitable for high-power calibers, and replaceable 18650 batteries ensure predictable performance during extended missions.
🎯 Who it is for
Primarily for military units, snipers, forward observers, reconnaissance and special tactical teams. Also suitable for professional users who require a thermal weapon sight with variable optics, an integrated laser rangefinder and a complete digital fire control system.
