A handheld hardlight projector that generates a 60-centimeter-diameter disc of semi-solid photonic matter, functioning as a personal shield capable of deflecting physical blows, absorbing low-velocity projectiles, and blocking chemical sprays. The PA-7 is the first consumer-grade hardlight product, adapted from Sterling-Nakamura's military hardlight barrier systems with drastically reduced power and duration to meet civilian safety standards and battery constraints.

The shield disc projects from a grip-activated emitter roughly the size of a flashlight handle. When activated, the disc materializes in approximately 0.3 seconds and maintains coherence for up to eight seconds per activation, with four activations per charge. The hardlight surface has the approximate stopping power of 6mm polycarbonate — sufficient to block a punch, a knife slash, or a low-velocity flechette round, but not rated against standard firearms ammunition or high-energy weapons.

Sterling-Nakamura prices the PA-7 at Φ2,400, firmly in the Tier 3-4 market segment. The device is marketed through personal security consultants and high-end lifestyle retailers, emphasizing its technological sophistication and the prestige of carrying hardlight technology. The limited eight-second activation window per use means the PA-7 is a reactive tool — something deployed in the critical seconds of an encounter rather than a sustained defensive system.
