Most digital night vision tops out around 600 yards and forces you to carry a separate rangefinder — different eye lines, fumbled handoffs, lost targets in the seconds between devices. The QE-B50 solves both problems: a 0.0005-lux Quantum Elite sensor pushes night detection past 1,100 yards while an integrated 1,635-yard laser rangefinder puts precise distance data into the same viewfinder. One device, one eye line, from target acquisition through confirmed range.

The faster f/0.9, all-glass, multicoated 50mm objective gathers more light than f/1.0 designs, feeding a UHD sensor that resolves 2880x2160 pixels for 4K video capture. Dual integrated illuminators — 850nm and 940nm — give you flexibility across lighting conditions, and the automatic internal filter handles the daylight-to-IR transition without manual intervention. A Class-I 905nm laser rangefinder returns distance out to 1,500 meters, and 18650 rechargeable batteries deliver up to 8.5 hours of runtime — nearly double the Quantum Digital's CR123A endurance.

Key Features

• 1,635-Yard Class-I Laser Rangefinder — Eye-safer Class-I 905nm LRF returns distance out to 1,500 meters without the restrictions of Class-3R lasers
• 1,100-Yard Night Detection — Dual 1-watt IR illuminators (850nm + 940nm, Class-3R) push detection range to 1,000 meters in total darkness
• Quantum Elite Sensor (0.0005 lux) — 75% more sensitive than the G3 generation, with a UHD 2880x2160 pixel sensor that captures detail invisible to lesser digital units
• 4K Video Recording — Capture 4K, 2K, 1080p, or 720p video at up to 60fps with built-in microphone; 16.1MP stills for evidence-grade documentation
• f/0.9 All-Glass Optics — Faster than f/1.0 designs, the multicoated 50mm objective maximizes light throughput from dusk through total darkness
• Electronic Image Stabilization — EIS at 6x optical magnification smooths handheld viewing and eliminates shaky video from unstabilized digital units
• Automatic Day/Night Filter — An internal color-enhancing filter switches automatically between daylight and IR modes — no manual cap removal, no missed moments
• Six Color Modes — Daytime Color, Nighttime Color, Black & White, NV Green Phosphor, NV White Phosphor, and Amber
• Dual 1024x768 AMOLED Displays — Independent eyepiece displays with deep blacks and wide viewing angles, ruggedized for cold-weather operation
• 8.5-Hour Battery Life — Runs on 2x or 4x 18650 rechargeable batteries, or connect via USB-C to a power bank for up to 24 hours of continuous operation

Ideal For

• Long-range hunters and marksmen who need 1,000+ meter night detection, instant ranging to 1,635 yards, and 4K documentation
• Search and rescue teams running extended operations with live Wi-Fi streaming and HDMI output to a command post
• Law enforcement and security professionals who need the highest-sensitivity digital night optic with recorded, time-stamped evidence and dual IR flexibility
• Serious wildlife researchers and astronomers who demand the best available sensor sensitivity and 4K capture in a handheld binocular platform
