2015 Vannevar Bush Fellow, Dr. Teri Odom, Develops Nanoscale Metalense Optical Elements

Using silver nanoparticles and a polymer, 2015 Vannevar Bush Fellow Dr. Teri Odom has developed a tiny lens that can change its shape and adjust its focus upon demand. The optical element is called a metalense . While glass causes chromatic aberrations by different wavelengths like a prism, a metalens uses tiny nanostructures to bend a wide spectrum light toward a focal point. "In this study, we demonstrated a versatile imaging platform based on fully reconfigurable metalenses made from silver nanoparticles," said Odom, "During a single imaging session, our metalens device can evolve from a single-focus lens to a multi-focal lens that can form more than one image at any programmable 3D position."
