The ability to correct the effects of spherical aberration in electron lenses, whether by software reconstruction or hardware correctors, allows direct interpretation of TEM images down to the information limit of the system.
A great advantage of the transmission electron microscope is in the capability to observe, by adjusting the electron lenses, both electron microscope images (information in real space) and diffraction patterns (information in reciprocal space) for the same region.
