META LENS AND OPTICAL APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18224990 titled 'META LENS AND OPTICAL APPARATUS INCLUDING THE SAME
Simplified Explanation
The abstract describes a meta lens that consists of two lens surfaces, one opposite to the other.
- At least one of the lens surfaces is a metasurface with nanostructures smaller than the wavelength of the light it operates on.
- The deflection properties of the two lens surfaces are opposite to each other in certain regions based on the position of the incident light.
- The meta lens is designed to operate within a specific wavelength band.
- The innovation lies in the use of metasurfaces with nanostructures to achieve the desired deflection properties.
Original Abstract Submitted
A meta lens includes a first lens surface, and a second lens surface provided opposite to the first lens surface, wherein at least one of the first lens surface and the second lens surface is a metasurface including a plurality of nanostructures having a sub-wavelength dimension that is less than a central wavelength λin an operation wavelength band of the meta lens, and wherein a deflection property of the first lens surface and a deflection property of the second lens surface based on positions of incident light are opposite to each other in at least some regions of each of the first lens surface and the second lens surface.
