Product Description
ThermTec ORYX-LR 635 Thermal Riflescope with ZEISS Rail
The ThermTec ORYX-LR 635 is a thermal riflescope with an integrated ZEISS rail and a built-in laser rangefinder up to 1,200 m. The 640 x 512 thermal sensor with NETD ≤15 mK and the 35 mm F0.8 lens deliver high-contrast, detailed thermal images even in rain and fog. With 2.6x base magnification and a wide field of view of 21.9 m at 100 m, the ORYX-LR 635 thermal scope is especially suited to stand hunting, stalking and hunting along the woodland edge. The integrated ballistic calculator also helps you work out the correct holdover.

The ORYX-LR 635 is suited to rifles with a ZEISS rail mount and mounting without rings.
ZEISS rail mounting
The difference to the ORYX-L 635 is the mount. Instead of a tube for rings, the LR model has a rail built into the housing. Seated in the mount, the scope levels itself to the rifle. The reticle doesn't cant, and no extra adjustment is needed.
Image: 640 sensor and large OLED display
At ≤15 mK the sensor is highly sensitive. Fine temperature differences stay visible in rain, fog or after a warm day. The image runs on a 1.03 inch OLED with 2560 x 2560 pixels - large, sharp and easy on the eye during long observation. AI image calibration works largely shutterless, so the image hardly ever freezes when the temperature changes. The detection range also reaches up to 1,800 m.
Measure the range, see the holdover
The laser rangefinder is integrated into the lens and measures up to 1,200 m. The ballistic calculator uses that distance and shows the corrected aiming point. Range is measured by laser only, never estimated.
TASS, RAV and zeroing
After a shot at high magnification, the ThermTec AutoSight System (TASS) automatically returns to base magnification, so you keep the game in a wide field of view. Recoil activated video (RAV) records the shot in 1280 x 1024 with sound. TASS works with RAV enabled.
Further features:
- up to 6 zeroing profiles
- Freeze zeroing
- 7 reticles in 6 colours
- Picture-in-picture function
Handling and battery
Focus with the central turret, zoom with a ring like on a traditional riflescope. The 21700 battery sits horizontally, stays out of your view and lasts up to 8 hours. It is replaceable, so a spare gets you through any night. Charging and data via USB-C, plus a Wi-Fi hotspot.
