ThermTec Ventus 635L – precise observation in any lighting condition
The ThermTec The Ventus 635L combines modern sensor technology with reliable performance for use day and night.
A highly sensitive thermal imaging sensor with <15 mK NETD works in conjunction with a 12-megapixel CMOS sensor and switchable IR illumination (850 nm / 940 nm). This results in clear and consistent images – regardless of lighting conditions. The integrated ThermTec AI calibration automatically optimizes sharpness and stability, ensuring a steady image even in dynamic situations. With balanced magnification and a detection range of up to 1800 meters, the device is ideal for quickly and efficiently scanning areas. Intuitive controls and an ergonomic design ensure comfortable viewing, even during extended use.
5-in-1 system – versatile technology in one device
The Ventus 635L combines five key features: highly sensitive thermal imaging (<15 mK), a powerful 4K Ultra CMOS camera, dual IR illumination, and an integrated laser rangefinder. This combination enables reliable detection, secure identification, and precise distance measurement – even in challenging terrain and under difficult conditions.
4K Ultra – impressive detail
The modern 4K Ultra CMOS sensor with 12 megapixels delivers high image sharpness and clear contrasts.
Together with the 0,5″ OLED display (1600 × 1200), this creates a particularly detailed and pleasant viewing experience.
Thermal Super Resolution – maximum detail even when zoomed in
The combination of basic magnification and stepless digital zoom up to 14,8x is complemented by AI-powered Thermal Super Resolution.
This ensures that even at high magnification, fine details remain visible and the image quality remains consistently high.
Ergonomic operation – comfortable and intuitive
The well-designed housing with optimized hand rest allows for stable and relaxed use.
The dual focus wheel control can be easily operated with one hand and allows for quick switching between different modes – regardless of the preferred hand.
Comfort and grip in all weather conditions
The robust, rubberized surface with anti-slip structure ensures a secure grip and remains flexible even at low temperatures.
The adjustable interpupillary distance of 60 to 72 mm allows for optimal adaptation to different users.
Efficient energy management for long deployments
Two 18650 batteries provide a runtime of up to 6 hours.
An integrated proximity sensor automatically switches off the display when the device is not in use – this saves energy and extends the operating time.
