Abstract:
An achromatized metasurface lens that includes a color filter array and a metasurface lens located proximate to the color filter array. The color filter array includes a plurality of color filter elements for different colors of light. The metasurface lens includes a corresponding plurality of subsets of nanostructures based on the color filter array. Each respective subset of nanostructures is optically aligned with a corresponding color filter element. For example, a subset of nanostructures configured to modify a particular color of light may be optically aligned with a color filter element that filters light of the same particular color. The achromatized metasurface lens may be incorporated into a display system, such as a head-mounted-display. The display system may also include a narrowband display source tuned to the color filter elements in the color filter array.
