Introduction to IREEDA F-GPNVG18

I. Core Design Principles and Structural Advantages

1. Four-Optical System: A Dual Breakthrough in Field of View and Depth of Field

The optical layout adopts a horizontal arrangement of "central dual tubes + outer dual tubes." The two central tubes are parallel and forward, providing stereoscopic depth perception comparable to binocular night vision devices, ensuring distance judgment and action coordination. The two outer tubes are offset to the left and right from the central axis, achieving seamless image fusion through chord-cutting stitching technology, ultimately achieving an ultra-wide 120° horizontal field of view and a vertical field of view of approximately 50°.

The main body is made of lightweight engineering plastics and nylon, with a battery-free weight of 770-912g. Even with an external battery pack, the total weight remains below 1kg. The helmet's weight distribution design balances the center of gravity, reducing neck strain during extended wear.

II. Core Performance Parameters and Technical Highlights

1. Image Intensifier Tube and Imaging Quality

Mainstream configuration includes a Gen2+/near Gen3 level 18mm image intensifier tube. Some high-end models use a GaAs cathode, achieving a resolution of 64-72 lp/mm, a quality factor (FOM) up to 2300, and a signal-to-noise ratio of 28-32, enabling clear identification of targets at 200 meters.

2. Intelligent Functions and Reliability Design

The power supply system supports a single CR123A lithium battery or a 4-cell CR123A external battery pack, providing 30-80 hours of battery life without infrared illumination.

Built-in multiple protection mechanisms: automatic brightness adjustment adapts to switching between strong and weak light; strong light protection against power failure to prevent damage from light source impacts; IP67 waterproof rating and a wide operating temperature range of -40℃ to +55℃, suitable for complex environments such as the wild, rainforests, and coastal areas.

Rich auxiliary functions: 850nm infrared illumination (20mW) meets the needs of completely dark environments; inter pupillary distance is continuously adjustable from 58-72mm and supports manual locking to adapt to the inter pupillary distance requirements of different users.

Compared to binocular night vision devices, the core advantage of foldable quad-lens night vision devices lies in their ultra-wide field of view, providing panoramic situational awareness. This eliminates the need for frequent head turns to cover the surrounding environment, significantly improving the speed of detecting flanking threats, making them particularly suitable for scenarios requiring rapid response, such as urban warfare and jungle raids. Their depth perception capability is comparable to binocular devices, and through simultaneous binocular gain optimization, they avoid the problem of decreased stereoscopic vision caused by widening the field of view.
