VENTUS 650L Dual Thermal Binoculars, ThermTec

VENTUS 650L Dual Thermal Binoculars, ThermTec

The thermal imaging unit features a sensor with a resolution of 640 × 512 pixels, a pixel pitch of 12 μm, and a high thermal sensitivity of NETD < 15 mK. These parameters ensure clear visualization of subtle thermal differences even in dynamic conditions or adverse weather (rain, fog). The 50 mm thermal lens with an F1.0 aperture offers a base magnification of 3.7× and a target detection range of up to 2,600 meters. A refresh rate of 50 Hz ensures smooth, stutter-free tracking.

The digital optical system utilizes a high-resolution CMOS sensor with 3536 × 3536 pixels (12 MP) and a 50 mm lens with an F1.4 aperture for sharp images day and night. Night mode is supported by an integrated infrared illuminator that can be switched between wavelengths of 850 nm (range up to 400 m) and 940 nm (range up to 350 m). The resulting image is displayed on a 0.5″ AMOLED screen with a high resolution of 1600 × 1200 pixels. It also features a built-in laser rangefinder with a range of 1,000 meters and an accuracy of ±1 meter. For comfortable binocular viewing, the binoculars are equipped with precise interpupillary distance adjustment in the range of 60–72 mm.

The binoculars offer user features such as electronic image stabilization (EIS), picture-in-picture (PIP), and automatic tracking of the hottest spots (Heat Track). The design stands out for its durability with an IP67 rating and operates reliably in temperatures ranging from –20 °C to +50 °C. Recordings are stored on 64GB of internal memory, and power is provided by two replaceable 18650 Li-ion batteries, which provide up to 6 hours of operation.
