Thermal Monocular ThermTec WILD 635L

ThermTec WILD 635L is a handheld thermal imaging monocular with an integrated laser rangefinder, combining a high-resolution 640 × 512 thermal sensor with a fast 35 mm F0.8 objective lens and a wide field of view.

The 640 × 512 / 12 μm sensor with NETD ≤18 mK provides detailed thermal imaging and helps distinguish small temperature differences in challenging weather and environmental conditions. The 35 mm F0.8 objective provides a 12.5° × 10° field of view and a detection range of up to 1800 m.

WILD 635L provides 2.0× optical magnification with continuous 1–4× digital zoom. The 0.39-inch 1024 × 768 AMOLED display provides a clear and detailed image, complemented by six colour palettes, Forest/Target modes, PIP and heat tracking.

The integrated 905 nm laser rangefinder measures distances up to 1000 m with ±1 m accuracy. The device also supports AI distance measurement and ThermTec's LRF-Boost functionality.

A joystick and focusing wheel make one-handed operation easy. The device includes 64 GB of internal storage for photos and videos, Wi-Fi connectivity and app control. A replaceable 18650 Li-ion battery provides up to 8 hours of operation, while the IP67-rated housing is designed for demanding outdoor conditions.
