Аннотация к книге "Electron microscope"

High Quality Content by WIKIPEDIA articles! An electron microscope is a type of microscope that uses an electron beam to illuminate a specimen and produce a magnified image. An electron microscope (EM) has greater resolving power than a light optical microscope and can reveal the structure of smaller objects because electrons have wavelengths about 100,000 times shorter than visible light photons. They can achieve better than 50 pm resolution and magnifications of up to about 10,000,000x whereas ordinary, non-confocal light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000x.
