transmission electron microscope principle pdf
翻訳 · The electron microscope is classified by its principle and structure into two types: the transmission electron microscope (TEM) and scanning electron microscope (SEM). The principle of the TEM is to obtain a transmitted electron image or an electron diffraction pattern from a specimen, by magnifying an image or a pattern formed by electrons transmitted through the specimen.
