In article number 1900324, Shumin Xiao, Qinghai, Song and co‐workers demonstrate a multi‐functional metalens doublet. By combining two metalenses for circular‐polarized light and non‐polarized light into a group, the function of the system can switch between camera lens, compound microscope, and Galileo telescope via the control of incident polarization and separation distance.

Metalens Doublet：自旋角动量控制的多功能全介电超颖表面Doublet（Laser Photonics Rev. 14（6）/ 2020）

在文章1900324中，肖淑敏，青海，宋和同事展示了多功能金属双峰。通过将两个用于圆偏振光和非偏振光的金属镜组合在一起，该系统的功能可以通过控制入射偏振和分离距离在相机镜头，复合显微镜和伽利略望远镜之间切换。
