“According to the latest reports from technology media, glass microprism has attracted much attention due to its excellent performance, but processing microprism arrays has always been a challenge. The research team proposed a new method of glass quasi anisotropic wet etching dominated by interface drilling and successfully prepared high-quality microprism array devices. This method breaks the traditional understanding of isotropic wet etching and provides an efficient and low-cost new approach for the preparation of glass microprism arrays and other devices. The brightness is significantly improved, which is expected to lead the new development of microprism applications.”
