Thermal Monocular PIXFRA Draco PFI-635N-4K

Thermal & Digital Binocular with Laser Rangefinder – 640 Sensor

This dual-spectrum thermal and digital binocular is designed for users who require maximum image quality, long detection range, and precise distance measurement. Equipped with a high-end 640 × 512 thermal sensor (NETD ≤15 mK), 4K digital optics, integrated laser rangefinder, and 940 nm IR illuminator, it delivers reliable performance in both day and night conditions.

Exceptional thermal performance
The advanced vanadium oxide uncooled sensor with 12 μm pixel pitch provides excellent thermal sensitivity, allowing clear identification of targets even in challenging weather. The 35 mm F1.0 lens enables detection distances of up to 1800 meters.

High-resolution digital channel
The digital optical system supports up to 4K resolution (3840 × 2160), delivering sharp and detailed daytime images. Multiple viewing modes and digital zoom provide flexibility across various observation scenarios.

Integrated LRF and IR illumination
A built-in laser rangefinder measures distances up to 1000 m with ±1 m accuracy, while the 940 nm IR illuminator offers effective night illumination up to 350 m. The IR illuminator is replaceable, ensuring adaptability in the field.

Advanced functionality
The device supports video recording, Wi-Fi connectivity, GPS, PIP (Picture-in-Picture), intelligent image processing technologies such as PIPS 3.0 and Smart IR, and multiple color palettes for thermal and digital viewing.
