Selective directional blackening of the glass substrate produces blackened glass in designated regions. Defense applications include low-light night vision and space optical imaging. AVG anti-halo optoelectronic glass for low-light night vision provides high ultraviolet, visible and near-infrared transmission in its active area, with an efficient light-absorbing layer formed from the substrate around that area to eliminate stray light and improve clarity. Civil applications include smart wearables and high-definition drone cameras. Light-blocking glass for wearables substantially improves monitoring accuracy for blood oxygen, heart rate, blood pressure and other vital signs. In drone cameras it also suppresses stray light and improves image contrast.
