VENTUS 635L Dual Thermal Binoculars, ThermTec

VENTUS 635L Dual Thermal Binoculars, ThermTec

The thermal imaging unit is equipped with a sensor featuring a resolution of 640 × 512 pixels, a pixel pitch of 12 μm, and a thermal sensitivity of NETD < 15 mK. These parameters ensure clear visualization of thermal differences even in adverse weather conditions, such as rain or fog. The 35 mm thermal lens with a high F0.9 aperture offers a wide field of view and a detection range of up to 1,800 meters. The 50 Hz refresh rate ensures a smooth, tear-free image when tracking moving targets.

The digital optical system features a CMOS sensor with a resolution of 3536 × 3536 pixels and a 50 mm lens with an F1.4 aperture for sharp images both day and night. For night observation, an integrated infrared illuminator is available with the option to switch 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-inch AMOLED display with a resolution of 1600 × 1200 pixels.

The device is equipped with a laser rangefinder with a range of 1,000 meters and an accuracy of ±1 meter. Electronic image stabilization (EIS), automatic tracking of the hottest spots (Heat Track), and picture-in-picture (PIP) are available. The device features a rugged IP67-rated housing, built-in 64GB storage, and is powered by two replaceable 18650 batteries, providing up to 6 hours of operation.
