The ThermTec Ibex 635L Thermal Imaging Rifle Scope combines high-resolution thermal imaging, advanced AI image processing and an integrated laser rangefinder in a rugged, field-ready design. Built for shooters who demand excellent image clarity and reliable long-range performance, it features a 640 × 512 thermal sensor with NETD below 18mK, paired with a high-performance 35mm F0.8 objective lens.

With a detection range of up to 1800 metres, the Ibex 635L helps identify heat sources at considerable distances, while its 50Hz refresh rate delivers smooth, responsive thermal imaging. Thermal Super Resolution enhances image detail when using digital zoom, and ThermTec AI Calibration helps maintain a clear, stable image across changing environmental conditions.

An integrated 1000m laser rangefinder provides accurate distance measurements, while the built-in ballistic calculator supports distance and angle compensation. ThermTec's AutoSight System (TASS) automatically returns the scope to its base magnification following a high-magnification shot, helping restore a wider field of view for continued observation.

Designed for demanding field use, the Ibex 635L features a high-resolution 1600 × 1200 AMOLED display, central turret focus system and 64GB internal storage. Recoil Activated Video (RAV), audio recording and a replaceable 18650 battery system complete a feature-packed thermal riflescope built around practical performance.

Why We Recommend It

The ThermTec Ibex 635L is an impressive thermal riflescope that brings together high sensor resolution, advanced image processing and useful shooting features at a competitive level of specification.

Its 640 × 512 thermal sensor and NETD below 18mK provide excellent potential for identifying subtle temperature differences, while the 35mm F0.8 lens and 1800m detection range make it particularly appealing for longer-range observation. Thermal Super Resolution also helps preserve image detail when using digital magnification.

One of the standout features is ThermTec's AutoSight System (TASS). Following a high-magnification shot, the scope automatically returns to its base magnification, giving you a wider field of view to continue observing without having to readjust manually. Combined with Recoil Activated Video, this makes for a particularly useful feature set.
