Product Overview
The QVS3140 long runtime binocular night vision goggle is a professional-grade optical device engineered for extended-duration missions in low-light and no-light environments. Equipped with high-performance GEN2+ image intensifier tubes (with GEN3 tubes available as an upgrade), this device delivers exceptional target detection and recognition capabilities even in complex, challenging conditions. Designed with ergonomics in mind, it features a compact, lightweight construction that minimizes headborne fatigue during prolonged use, making it an ideal choice for professional users who demand reliable performance over long hours.
Core Advantages & Features
Extended Runtime for Uninterrupted Operations
The QVS3140 stands out with its industry-leading power management system. It comes standard with an external battery compartment and power cable, allowing users to extend operational time significantly. The device offers up to 80 hours of standby time and an impressive 10,000 hours of total service life, ensuring it remains operational throughout the longest missions without frequent battery changes.
Ultra-Lightweight Helmet-Mounted Design
Weighing only 500g for the main unit (620g total with batteries), the binocular night vision goggle effectively reduces headborne load compared to bulkier alternatives. The included special helmet bracket is compatible with FAST helmets and tactical bulletproof helmets, providing a secure, comfortable fit. The external battery box also doubles as a balanced helmet counterweight, further enhancing wearability during extended operations.
Superior Optical Performance
Powered by GEN2+ or GEN3 image intensifier tubes (green tube as standard, white phosphorus tube optional), the QVS3140 delivers bright, clear imaging with a signal-to-noise ratio of 22-25 and a resolution of ≥64lp/mm. It features a 40° field of view, 1× optical magnification, and a diopter adjustment range of -5D to +3D, ensuring sharp vision for users with different visual acuity. The F1.2 lens system provides excellent light gathering capability, and the recent focus distance of 0.25m allows for close-quarters observation.
Rugged & Intelligent Construction
With an IP67 protection rating, the QVS3140 is fully dustproof and waterproof, capable of withstanding harsh weather conditions and rough handling. It includes built-in strong light protection to prevent damage from sudden bright light sources and a direction-sensitive standby function that automatically powers off when not in use, conserving battery life.
Applications & Suitable Scenarios
The QVS3140 gen 2+ night vision goggle is versatile enough for a wide range of professional applications:
Professional security patrols and perimeter monitoring
Industrial inspection and maintenance in low-light facilities
Outdoor adventure and exploration expeditions
Search and rescue operations in remote, dark areas
Border and coastal surveillance missions
Wildlife observation and research at night
