Four independent tubes working with for independent lens. The two lens in the center works in the traditional way, whose direction is straightly forward to detect the target in distance. The other two tubes at the right or left side are designed for widening the field. The image from the right two tubes and the left two tubes can fuse to form a 120 degree view, which is a revolutionary development. The right two tubes and the left two tubes has its own independent imaging system and can be attached on a helmet mount similar with the ANVIS for free adjustment. It can also work as the handheld night vision whose interpupillary distance can be adjusted.
