Optical performance improvement of Cooke triplet based on meta-corrector
Year: 2025
Type: article
Abstract: We demonstrate a hybrid optical system that integrates a meta-corrector with a conventional Cooke triplet to improve focusing performance significantly. In this study, the Cooke triplet offers primary focusing, while the meta-corrector compensates for spherical aberration with a smooth phase profile. This design enhances spatial resolution and simplifies fabrication. Experimental results show that the focal spot size decreases from 5.68 μm to 4.03 μm, approaching the diffraction-limited Airy radius of 4.11 μm, validating the effectiveness of the meta-corrector. This approach provides a promising pathway for enhancing traditional lens systems and can be extended to advanced commercial optics for compact, high-performance imaging.
