HATSEN PVS31 NVG Protection Lens Cover, Adjustable Iris Light Shield, O-Ring Debris Seal, 6061-T6 Aluminum, Fits GPNVG (38mm) & PVS-31 Night Vision Device (31mm/32mm Objective Lens OD), Black

• Crafted from high-strength 6061-T6 aluminum, this lens cap withstands harsh field conditions with impact resistance. Built-in O-ring seal creates a dustproof, waterproof barrier, safeguarding 31mm-38mm objective lenses of night vision devices (PVS-31, GPNVG, etc.) for long-lasting use in outdoor and complex scenarios.
• Unlike traditional friction caps, it threads directly onto the objective lens for a tight, slip-proof connection—prevents accidental dislodgement during use. Precisely matches PVS-31 series lens threads for easy installation/removal, ideal for high-intensity activities or sudden movements.
• Rotate the turret to switch apertures freely (1mm-23.5mm), adapting flexibly from low to bright light environments. Built-in 5.66mm tactile stop enables quick reset to infinity focus without recalibration, enhancing nighttime operation efficiency.
• Includes a polycarbonate sacrificial lens with 92% light transmission—shields the objective lens from scratches and impacts while ensuring sharp, distortion-free images. Lenses are individually replaceable, reducing maintenance costs for long-term use.
• Fits PVS-31, GPNVG, and other night vision devices with 31mm-38mm objective lens OD. Compatible with third-party PVS-14 style accessories (e.g., LIF lenses, sacrificial lenses) and supports attachments with OD ≤32.4mm. Universal design requires no modifications for easy integration.
