Scientists create a low-cost, high-precision glass nanoengraving technique

In a joint study, a collaborative of Russian scientists has developed a mechanism of laser deposition of patterns on glass with a resolution of 1000 times lower than the width of a human hair. The lasers were focused through small glass spheres, rather than traditional lenses. This mechanism allows application of complex patterns to a glass surface relatively easily and inexpensively, obtaining a spatial resolution of less than 100 nanometers.
