Magnification of sem microscope

WebThe scanning electron microscope was first made by a German researcher and applied physicist and inventor Manfred von Ardenne in 1937. The magnification of a scanning electron microscope typically ranges from 20X to approximately 30,000X. The spatial resolution range of a scanning electron microscope is from 50 to 100 nm. WebFE-SEM is a type of electron microscope that generates the image by scanning the sample surface with a high energy electron beam focused onto the sample surface. TEM is a …
