Description
A unique microscope, invented in 1951, that requires no lens system. In a field emission microscope, a positively charged specimen is placed in a glass chamber with a strong electrostatic field. Positively charged ions in the chamber are repelled by the sample and attracted to a negatively charged fluorescent screen producing an image of the atomic structure in the specimen. Magnifications of one million times have been obtained.
