Blackened Glass
Through high-precision selective directional blackening of the glass substrate itself, blackened glass in designated areas is obtained. Among them, the AVG anti-halo photoelectric glass used for low-light night vision has high transmittance for UV, visible and near-infrared in the effective area, while a high-efficiency light-absorbing layer is generated from the substrate itself around the effective area, which can eliminate stray light and improve clarity; the ultra-light-blocking glass used for smart wearables can greatly improve the accuracy of vital sign data monitoring.
