Multi-spectrum binoculars ThermTec Ventus 335L

The ThermTec Ventus 335L is an advanced multispectral imaging device designed for detailed observation in a wide range of environmental and lighting conditions. Combining a high-sensitivity thermal sensor with a 4K Ultra CMOS digital sensor, it delivers clear, detailed images both day and night. Its compact, ergonomic design ensures comfortable one-handed operation, making it an excellent choice for extended observation in the field.

The 384 × 288 thermal sensor with NETD below 15 mK provides outstanding thermal sensitivity, helping detect subtle temperature differences even in challenging conditions. The advanced 4K Ultra CMOS sensor captures highly detailed digital images, while the 1600 × 1200 AMOLED display delivers a sharp and immersive viewing experience.

ThermTec AI Zoom enhances digital magnification through intelligent image reconstruction, helping preserve fine details and textures at magnifications of up to 30×. Electronic Image Stabilization (EIS) reduces image shake during high-magnification observation, while ThermTec AI Calibration optimizes image stability and minimizes interruptions during use.

The innovative hybrid Picture-in-Picture (PIP) mode combines thermal and digital imaging in a single view, allowing users to examine target details while maintaining awareness of the surrounding environment. Switchable 850 nm and 940 nm infrared illumination supports nighttime observation, with viewing ranges of up to 400 m and 350 m, respectively.

An integrated laser rangefinder measures distances of up to 1,000 m with an accuracy of ±1 m. Additional features include a digital magnetic compass, azimuth indication, heat tracking, photo and video recording, audio recording, and 64 GB of internal eMMC storage.

Designed for demanding outdoor use, the Ventus 335L features a durable, ergonomically balanced housing with an IP67 protection rating against dust and water. Weighing just 825 g and measuring 164 × 127.6 × 73 mm, it remains comfortable to carry and operate during extended observation sessions. Two replaceable 18650 lithium-ion batteries provide up to 7 hours of operation, supporting reliable performance during longer trips and field activities.
