A new type of achromatic metalens has been developed by researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS). This metalens is able to change its focal length without changing its physical shape, enabling the lens to dynamically adjust its focus for a variety of tasks. This new lens could lead to more efficient and compact optical systems for cameras, microscopes, and other imaging devices.

Researchers at SEAS have developed an achromatic metalens that can dynamically adjust its focal length without changing its physical shape. This new lens is able to focus on objects at different distances without distortion or chromatic aberration, meaning that it can produce a clear image regardless of the object’s position. This breakthrough could lead to more efficient and compact optical systems for cameras, microscopes, and other imaging devices.
