Tiny tubes and far away stars—large metalens images the night sky

By Guest Contributor / March 5, 2024

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences developed a method for creating 100-millimeter-diameter metalenses. Scaling up metalenses to this size makes applications in astronomy and free-space optical communications possible.

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.
