以高空间分辨率塑造光的振幅和相位的所谓平面光学器件目前受到相当多的关注。许多期刊出版物似乎都对具有高效率、高数值孔径、宽带操作的超平面超透镜的巨大前景抱有希望……我们通过参考超透镜的历史背景现状、评估最近解决的技术和科学挑战并批判性地识别仍然存在的障碍，来调节期望。
The so-called flat optics' that shape the amplitude and phase of light with high spatial resolution are presently receiving considerable attention. Numerous journal publications seemingly offer hope for great promises for ultra-flat metalenses with high efficiency, high numerical aperture, broadband operation... We temperate the expectation by referring to the current status of metalenses against their historical background, assessing the technical and scientific challenges recently solved and critically identifying those that still stand in the way.
