超级放大镜头让人看到从未见过的细节

美国的两个物理学家团队独立地创造出了第一台使用具有负折射系数的元材料的真正超级放大镜头。与传统镜头不同的是,超级镜头可以提供几乎无限分辨率的图像。这样,也许在某一天,能够通过它来实现蛋白质、病毒、DNA等的光学成像。

Magnifying superlenses show more detail than ever before (Mar 22)

Two teams of physicists from the US have independently created the first truly magnifying "superlenses" using metamaterials with a negative index of refraction. Unlike conventional lenses, superlenses can provide images of almost limitless resolution, and could one day enable the optical imaging of proteins, viruses and DNA.
