From grain-sized to centimeter scale—technique makes mass production of metalenses possible

By Lisa McDonald / December 13, 2019

Metalenses, or flat surfaces that use nanostructures to focus light, are poised to revolutionize cameras, sensors, and displays—if the lenses can be mass produced. Researchers at the Harvard School of Engineering and Applied Sciences found deep-ultraviolet projection lithography can solve this production challenge.
