New metalens outperforms the human eye and could be the future of optical technology

Scientists have created a lens that not only helps you see better, but is also capable of making a breakthrough in the field of

optical equipment.

What is known

Researchers from the School of Engineering and Applied SciencesJohn A. Paulson Sciences at Harvard University created a lens based on artificial muscle technology. The new metalens works on the principle of the human eye and can focus on objects in real time. In addition, the lens is able to correct astigmatism and image shift, which prevent a person from seeing the world around him clearly. Yes, and in size it is smaller than classic lenses.

Metalens is superior to its “classical brother”and in terms of design. Thanks to nanoparticles, the lens can focus light, capturing the spectrum visible to humans. At the same time, classic lenses use several elements to achieve this effect.





This is already the second version of the metalens.The first samples were too small to use the technology in areas other than medicine. Now, researchers have managed to create a metalens that is one centimeter larger. The more, the better, because then the technology can be applied, for example, in cameras. The lens should be large enough to cover the sensors and not create a vignetting effect.

Metallenses will not reach consumer electronics any time soon, but scientists are already assessing the potential of the technology. In addition to cameras, such lenses are useful for augmented and virtual reality.
