Product Description
ThermTec Ventus 650L Night Vision and Thermal Imaging Binoculars with LRF
The ThermTec Ventus 650L thermal imaging binoculars with laser rangefinder combine thermal imaging technology, digital day and night vision, and classic binocular observation in a single device. This multispectrum binocular integrates a 640x512 VOx thermal sensor, a 4K UHD CMOS sensor, and a switchable IR illuminator with 850 nm and 940 nm.
This allows heat sources to be detected quickly, game to be clearly identified, and distances to be measured precisely. Thanks to the binocular design, observation is carried out with both eyes, which is significantly more comfortable during longer viewing sessions.
With a detection range of up to 2,600 m and a large 0.5-inch AMOLED display with 1600x1200 px, the ThermTec Ventus 650L delivers a high-contrast and detailed image in daylight, at dusk, and during night observation. Within the Ventus series, this model is designed for long observation distances and is particularly suitable for open terrain and large field areas.

Highly sensitive 640x512 thermal sensor
The thermal sensor of the ThermTec Ventus 650L operates with a thermal sensitivity of less than 15 mK (NETD), allowing even very small temperature differences to be displayed clearly.
Especially under challenging conditions such as fog, rain, high humidity, or low temperature contrast between game and surroundings, the image remains high-contrast and detailed. The integrated Thermal Super Resolution technology further enhances the display of fine details.
4K day and night vision channel
In addition to the thermal channel, the Ventus 650L from ThermTec features a 4K Ultra HD CMOS sensor with 3536 x 3536 px resolution. This provides clear and detailed images in daylight as well as in digital night vision mode.
The detachable IR illuminator offers two wavelengths:
-
850 nm: for maximum range
-
940 nm: for shorter distances where minimal visible glow is preferred
The wavelength can be conveniently switched using the rotary control.
AMOLED display and AI Zoom Pro
The 0.5-inch AMOLED display provides a clear and high-contrast image with high pixel density, even in low temperatures. The AI Zoom Pro function also optimizes image quality when using digital magnification, ensuring that both target objects and background details remain clearly visible.
Picture-in-Picture function and stabilized image
With the Picture-in-Picture (PiP) function, thermal and digital channels can even be displayed simultaneously. This significantly simplifies locating and identifying game.
An integrated EIS image stabilizer reduces image movement and provides a steadier display, even at higher magnification levels.
The feature set is complemented by additional functions such as hot spot tracking, various color palettes, and dedicated image modes for forest and rainy conditions.
Ergonomic thermal binoculars
The ThermTec Ventus 650L was developed as a binocular thermal device. Observing with both eyes provides a more natural viewing experience and reduces eye fatigue.
With an adjustable interpupillary distance of 60 to 72 mm and a diopter adjustment of ±5 dpt, the thermal binoculars can be individually adapted to different vision requirements. The dual focusing wheels for thermal and digital channels also allow quick and precise focusing.
Replaceable battery system
Two standard 18650 batteries provide a runtime of approximately 6 hours, and thanks to the quick battery replacement system, operating time can easily be extended.
An integrated proximity sensor automatically switches off the display when the binoculars are moved away from the eyes. This helps save energy and extend battery life.
