The VENTUS 650L is an advanced “5-in-1” thermal and digital binocular designed for professional use. It features a highly sensitive thermal sensor with an optimized NETD of <15 mK, ensuring clear imagery even with minimal temperature differences. A 12 MP CMOS sensor, combined with switchable 850 nm and 940 nm IR illumination, enables reliable observation during the day and in total darkness.
ThermTec AI Calibration technology enhances image clarity and stability, ensuring a smooth, detailed view even in dynamic environments. A detection range of up to 2,600 meters and balanced zoom capabilities allow for efficient area scanning and precise object identification.
The combination of <15 mK thermal sensitivity, a 4K Ultra CMOS sensor, dual-wavelength IR illumination, and a precision laser rangefinder ensures versatile performance in daylight, twilight, and total darkness. It is a reliable solution for challenging terrain and demanding outdoor conditions.
Base optical magnification, paired with continuous digital zoom up to 14.8x and AI-powered Thermal Super Resolution (TSR) technology, delivers exceptionally detailed, high-quality imagery. The ergonomic body design, featuring palm and arm support, allows for one-handed operation of the dual focus wheel and easy switching between hands. The rugged, rubber-coated, non-slip housing remains flexible even in low temperatures. An adjustable interpupillary distance (60–72 mm) ensures comfortable use.
Two swappable 18650 Li-ion batteries provide up to 6 hours of runtime. A proximity sensor automatically turns off the display when the device is not in use, thereby conserving energy. Thermal imaging module
