• The lens cap for night vision devices is made of 6061-T6 aluminum alloy body, designed for harsh field environments with high strength and impact resistance. The built-in O-ring seal forms a dustproof and waterproof barrier to keep out dust, providing long-lasting protection for the 31mm-38mm objective lenses of night vision devices such as PVS-31 and GPNVG, which are suitable for complex scenarios such as tactical operations and outdoor adventures.
• Unlike the traditional friction lens cap, it is threaded directly onto the objective lens to ensure a tight and non-slip connection, avoiding accidental dislodgement and loss during use. Precisely adapting to the threads of PVS-31 series objective lenses, it is easy to mount and dismount, providing reliable protection for high-intensity sports or sudden movements.
• Rotate the turret to realize the free switching of 1mm-23.5mm aperture range, supporting the flexible adaptation from low light to strong light environment. The built-in 5.66mm tactile positioning stop can be quickly reset to infinity focusing state without repeated calibration, which improves the efficiency of nighttime operation and copes with sudden light changes.
• Equipped with sacrificial polycarbonate protective lenses with 92% light transmission, which protects the objective lens from scratches and impacts, and ensures clear and distortion-free images of night vision equipment. The lenses can be replaced individually, reducing maintenance costs and suitable for long-term high-intensity use.
• Suitable for PVS-31, GPNVG and other night vision devices with 31mm-38mm OD objective lens, compatible with third-party PVS-14 style accessories (e.g., LIF lenses or sacrificial lenses), and support the installation of accessories with OD ≤ 32.4mm. Universal design to meet the needs of diverse equipment, no additional modification, ready to use.
