Multi-spectrum binoculars ThermTec VENTUS 650L

The VENTUS 650L is equipped with a highly sensitive thermal sensor featuring optimized NETD <15 mK, ensuring exceptional image clarity even in minimal temperature differences. A 12 MP CMOS sensor combined with switchable 850 nm and 940 nm IR illumination delivers reliable performance both in daylight and complete darkness. 
Powered by ThermTec AI Calibration, the device enhances image sharpness and stability for smooth viewing in dynamic environments. With a detection range of up to 2600 m and balanced magnification, it enables efficient target scanning and precise identification at long distances. 
By integrating NETD <15 mK thermal sensitivity, a 4K Ultra CMOS sensor, dual-band IR illumination, and a precise laser rangefinder, the VENTUS 650L ensures versatile, high-confidence imaging across daylight, twilight, and total darkness. It is built to perform in complex terrain and demanding field conditions. 
Base optical magnification combined with continuous digital zoom up to 14.8×, enhanced by AI-powered Thermal Super Resolution (TSR) technology, delivers ultra-detailed, premium-quality images. 
The ergonomic body design with waist and hand support allows dual focus wheel control with one hand and effortless switching between hands. The durable rubber-coated housing with anti-slip texture maintains elasticity in low temperatures. Adjustable interpupillary distance (60–72 mm) ensures comfortable use for different users. 
Two replaceable 18650 Li-ion batteries provide up to 6 hours of operation. A built-in proximity sensor automatically turns off the display when no presence is detected, helping conserve battery life.
