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.
