Electron microscopes suffer from optical aberrations much like the ones that add a fringe of color to the images seen with a magnifying glass. Now a fix is in sight: a corrective “electron mirror” that precisely counteracts the aberrations introduced by the electron lens. The mirror could increase the resolution of some high-powered electron microscopes by a factor of 5 or more.
