The art of magnifying the small reached a new plateau in 1955 when the German-born American physicist Erwin Wilhelm Mueller, who had developed the field-emission microscope (see 1937), devised the field ion microscope, which emitted beams of ions rather than electrons.
Which is why, in addition to offering high-end field-emission microscopes like the newly introduced field-emission JSM-7800F, which can achieve 0.8-nm resolution, lower-end instruments like the benchtop NeoScope help introduce new users to electron microscopy.
