NIGHT VISION F-PVS-31,Gen 2+, Green Phosphor, FOM 1800

• Dual‑channel fusion system – Combines low‑light image intensification and thermal imaging for ultimate situational awareness.
• Multiple operating modes – Select low‑light only, thermal only, or various fusion overlays (edge‑detection, full‑color blending, etc.).
• High‑performance low‑light channel – Gen 2+ or Gen 3 IIT with manual gain, 1× magnification, 40° FOV, and clear imagery.
• Advanced thermal channel – 640×512 Vox detector, 12μm pixel, 26°×20° FOV, and high‑resolution display (≥1024×768).
• Rich false‑color palettes – White Heat, Black Heat, Green Heat, Rainbow, Metal, Edge, Highlight, and Breathe for easy target discrimination.
• Electronic zoom, compass, and pitch indicator – Provides range estimation and orientation data.
• Wi‑Fi connectivity – Remote viewing, photo/video capture, and firmware updates via mobile APP.
• Built‑in recording – On‑board photo, video, and playback functions.
• Independent focus and adjustments – Manual focus for both channels; brightness and contrast control for thermal.
• Binocular design – Reduces eye fatigue and enhances depth perception.
• Wide interpupillary adjustment – 58‑78 mm with comfortable eye relief.
• Diopter adjustment – -4 to +2 D to fit most users without glasses.
• External battery box – Powered by two 18650 rechargeable batteries, easily replaceable in the field.
• Lightweight and compact – Only 660 g (without battery) in a 125×105×94 mm housing.
• Rugged and weatherproof – IP65 standard (IP67 optional), -20°C to +50°C operating temperature.
• Exceptional detection range – Detect human at 1000 m and cars at 2500 m; identify human at 400 m and cars at 1000 m.
• Versatile application – Ideal for military, law enforcement, search and rescue, surveillance, and night navigation.

The F‑PVS‑31 represents the next generation of night vision technology, fusing the strengths of image intensification and thermal imaging into a single binocular system. The low‑light channel provides high‑resolution, low‑noise images in starlight or moonlight, while the thermal channel detects heat signatures through smoke, fog, dust, and complete darkness. The fusion algorithms combine these feeds to create a composite image that highlights targets in their environment, greatly improving detection, recognition, and identification capabilities. Users can choose from multiple operating modes: low‑light only, thermal only, or various fusion overlays (e.g., thermal edge‑detection overlaid on low‑light, or full‑color thermal blending). False‑color palettes allow quick adaptation to different backgrounds and personal preferences. The binocular offers manual focus for both channels, independent brightness and contrast adjustments, and digital zoom. The built‑in electronic compass and pitch indicator provide orientation data, while Wi‑Fi connectivity enables remote viewing, photo/video capture, and firmware updates via a mobile APP. The interpupillary distance is adjustable from 58‑78 mm, and the diopter range (-4 to +2) accommodates most users. The rugged housing is waterproof (IP65, IP67 optional) and operates in temperatures from -20°C to +50°C. Power is supplied by an external battery box holding two 18650 rechargeable cells, ensuring long runtime and easy field replacement. Detection ranges are impressive: a human‑sized target (1.7 m) can be detected at 1000 m and identified at 400 m; a car (5 m) can be detected at 2500 m and identified at 1000 m. The F‑PVS‑31 is a versatile, high‑performance tool for night navigation, surveillance, search and rescue, and tactical engagement.
