JAKE SALTZMAN, NEWS EDITOR [email protected]CHAMPAIGN, Ill., Dec. 15, 2020 — A team of researchers from the University of Illinois has developed a spherical lens capable of allowing incoming light — from any direction — to be focused on the lens’s surface opposite the input direction into a very small spot. The lens is one of multiple microlens designs the researchers introduced, each of which are 3D printed and feature adjustable refractive indices. Standard lenses have a single refractive index and, as a result, only a single access point for incoming light to travel through the lens. With the ability to precisely control both the shape of the lens...Read full articleRelated content from Photonics MediaArticlesTerahertz Generation Method Targets Ultrafast ElectronicsTerahertz (THz) waves can be used to probe the magnetic properties of new materials.
