What are the breakthroughs in the application of animorphic lenses?

The breakthrough in the application of animorphic lenses is mainly reflected in two aspects: optical performance optimization and structural innovation:
Breakthrough in the application of Fresnel lenses
Fresnel lenses achieve a combination of lightweight design and efficient optical performance by decomposing the curved surface of a convex lens into multiple micro prism rings. For example, in aviation obstacle lights, the divergent light emitted by LED light sources is converged into parallel beams, allowing the beam range to reach more than 20 kilometers, solving the bottleneck of traditional lens weight and efficiency.  ‌
Technological breakthrough of quasi achromatic superlens
The quasi achromatic meta lens (QAML) developed by the Zhejiang University team relaxes the bandwidth, aperture, and numerical aperture (NA) limitations of traditional achromatic lenses through phase extension technology, achieving broadband achromatic function with large aperture and high NA. This technology solves the color difference problem caused by the limited processing accuracy of traditional superlenses and provides a new solution for high-performance optical components.  ‌
Efficiency improvement in the field of laser processing
Optical shaped sheets are specially designed to improve processing accuracy and efficiency in laser cutting, welding, and marking. For example, the use of animorphic lenses in laser processing equipment can achieve micrometer level precision control, significantly improving production efficiency.
