The PVS-21 Low Profile Night Vision Goggle has been designed for aggressive special operations capability in air, water, and land environments . The patented low profile design offers 3-4 inches less protrusion than conventional night vision goggles enabling a wide range of mission applications. GPNVG-18 mainly solves the problem of field of view through the superposition of four night vision devices. However, compared with GPNVG-18, the PVS-21 low-light night vision device achieves both depth of field and field of view, and also adopts laser holographic pro...
