The ThermTec Ibex 635L is a thermal tube riflescope designed for target identification and aiming in low-light and nighttime hunting conditions. Built on a standard 30 mm main tube housing, the unit integrates a 640 × 512 uncooled VOx thermal sensor with a sub-18 mK NETD rating and a 35 mm F0.8 Germanium objective lens. It delivers a 2.2× optical base magnification paired with an integrated 1000 m laser rangefinder (LRF) and onboard ballistic calculation, providing precise shot placement on a 1600 × 1200 AMOLED display. Weighing approximately 770 g, it is recoil-rated up to 6,000 Joules to withstand high-power calibres including .308 Win, .30-06, and .300 Win Mag.

Key Features

• Integrated 1000 m LRF & Ballistics: Features a built-in laser rangefinder accurate to 1,000 m with an integrated ballistic solver to calculate real-time holdovers.
• High-Sensitivity Thermal Core: Uses a 640 × 512, 12 µm sensor with NETD < 18 mK and a 50 Hz frame rate for detailed thermal imaging across a detection range of up to 1,800 m.
• ThermTec AutoSight System (TASS): Automatically returns the display to the 2.2× base magnification after a high-magnification shot to preserve field of view for tracking moving game.
• Central Turret Focus: Replaces traditional objective-ring focus with an accessible central turret adjustment for one-handed operation from shooting positions.
• Recoil-Activated Video (RAV): Records video with audio automatically before and after the shot, alongside AI shutterless calibration and Thermal Super Resolution (TSR).
• Field-Swappable Power: Runs for up to 6 hours on a single removable 18650 Li-ion battery, with onboard 5V USB-C charging capability.

Who is the Thermtec Ibex 635l Thermal Tube Scope for?

• Nighttime predator and feral pest hunters — benefits from the 640 × 512, 12 µm VOx sensor with sub-18 mK sensitivity to resolve fine thermal details on pigs, wild dogs, and foxes, while the 770 g thermal tube riflescope maintains balance on mobile hunting setups.
• Medium-range and long-range deer hunters — utilises the built-in 1000 m laser rangefinder paired with onboard ballistic calculations and a 35 mm F0.8 objective lens to place precise shots across open paddocks up to its 6,000 Joule recoil limit.

Less suitable for: Wide-angle close-quarters scanning in dense brush, where a short focal length scope with a 20 mm lens provides a broader field of view; or extreme-range identification beyond 1,800 m, which requires a dedicated long-range optic with a 50 mm objective lens and higher base magnification.
