N2 - A high-performance all-dielectric lens, formed by integrating a conventional plano-convex lens with a high-indexmicrosphere lens (PCM), was developed for far-fieldsuper-resolution applications. The PCM lens features atheoretical resolution of ∼ λ/2.5 in air with a WD ∼ 2 µmaway from the lens. When combined with a femtosecondlaser, the actual patterning resolution can reach ∼ λ/3.5.The unusual focusing properties were theoretically andexperimentally verified, and direct laser nano-writing ofarbitrary patterns and nanostructures on various substrateswas demonstrated. This Letter can be naturally extendedto other super-resolution applications, including imaging,sensing, and trapping, with the potential of developing nextgeneration low-cost direct laser nano-m
