Super apochromatic supersurface composite microlens

Abstract

The invention discloses a super apochromatic supersurface composite microlens, which comprises a first lens and a second lens, wherein the first lens is a positive-focal power supersurface lens with anegative dispersion property, and the particular structure is a nano-antenna array with a wide spectral response; the second lens is a positive-focal power spherical reflection microlens with a positive dispersion property, and the particular structure is a flat convex spherical microlens; the first lens comprises an upper surface and a lower surface of the nano-antenna array; the second lens comprises a second lens plane side and a second lens curved surface; the lower surface of the first lens is mutually overlapped with the plane side of the second lens; and the nano-antenna array of the first lens is embedded inside the curved surface of the second lens. The technical problems that a complex optical system is needed for chromatic aberration correction of a positive-refractive index material, and the supersurface material needs to sacrifice a bandwidth and a numerical aperture in order to correct the chromatic aberration can be solved, and the super apochromatic supersurface composite microlens has the advantages of simple structure and miniaturization.

AI Technical Summary

Benefits of technology

This patented technology improves upon existing designs that use multiple layers or special materials to achieve specific functions such as high resolution imagery (HRI) systems. By optimizing the arrangement of different components within each layer, this new method allows for more efficient transmissions over longer distances without increasing their size. Additionally, due to its simplified construction, there are fewer parts needed than previous methods while still maintaining good image quality at larger sizes. Overall, these improvements improve performance and reduce bulkiness compared to current technologies used on HRIs.

Problems solved by technology

Technological Problem: Current methods for reducing color distortion involve adjusting various factors such as thicknesses of layers within the device's substrate layer, depth of penetrations into the device, alignment between multiple components, etc., leading to complexity and difficulty in manufacturing these types of microscopic opticals without sacrificial effects like excessively large dimensions and poor performance.
