Description
Infinity Cap PVS-31A – Rugged NVG Iris with Click-Stop™ Infinite Focus
The Infinity Cap PVS-31A is a mission-ready accessory designed to deliver maximumprotection and unmatched adjustability for your night vision device. Built from 6061-T6 aluminum and anodized to MIL-A-8625F Type II Class 1 & 2 standards, this cap is engineered to withstand battlefield abuse while preserving optical performance.
Unlike friction-fit covers, the Infinity Cap threads securely onto the NVG objective lens, preventing accidental detachment. A built-in O-ring seal keeps dust and debris out, while the integrated polycarbonate sacrificial lens ensures your expensive PVS-31A optics remain protected against scratches and impact — without sacrificing light transmission (92% clarity).
The defining feature is its adjustable iris system, which ranges from 23.5mm down to 1mm, allowing precise control over light intake and depth of field. The patent-pending Click-Stop™ technology provides tactile feedback at 5.66mm, instantly setting your optic to infinite focus. This enables rapid transitions between environments — from wide-open low-light operation to restricted aperture control in brighter conditions.
