Harvard SEAS develops millimeter-scale flat metalenses 28 Jan 2021 Capasso group forms 2mm achromatic metalenses that focuses RGB with mini display for AR, VR applications. In 2018, the Capasso’s team developed achromatic, aberration-free metalenses that work across the entire visible spectrum of light. But these lenses were only tens of microns in diameter, too small for practical use in virtual and augmented reality systems. Now, the researchers have developed a two-millimeter achromatic metalenses that can focus RGB wavelengths without aberrations and developed a miniaturized display for virtual and augmented reality applications. The research is published in Science Advances. “This state-of-the-art lens opens a path to a new type of virtual reality platform and overcomes the bottleneck that has slowed the progress of new optical device,” said Capasso, who is the Robert L. Wallace Professor of Applied Physics and Vinton Hayes Senior Research Fellow in Electri
