Onick NVG-D4 multi-function low-light night vision device uses a high-performance quasi-third-generation image intensifier, which has excellent performance, small size, light weight, clear imaging, simple operation, and flexible use. There are four independent image intensification tubes, and four independent objective lenses are arranged in a panoramic direction. The two lenses in the middle point forward like traditional double-tube goggles, giving the operator more depth perception, while the other two lenses point slightly outward from the center to increase the peripheral vision. The two tubes on the right and the two tubes on the left are spliced at the eyepiece. The operator sees that the two center tubes overlap with the two outer tubes to produce an unprecedented 120° field of view. The night vision device has a built-in infrared auxiliary light source and is highly practical. It can be used for observation, border and coastal defense reconnaissance, security surveillance, evidence collection, customs anti-smuggling, etc. in an unlit environment at night. It is an ideal equipment for security departments and guard patrols.
