WebThe electron beam follows a vertical path through the column of the microscope. It makes its way through electromagnetic lenses which focus and direct the beam down towards the sample. Once it hits the sample, other electrons ( backscattered or secondary) are ejected from the sample. Detectors collect the secondary or backscattered electrons, and WebHow does TEM work? An electron source at the top of the microscope emits electrons that travel through a vacuum in the column of the microscope. Electromagnetic lenses are …
WebThe scanning electron microscope (SEM) produces images by scanning the sample with a high-energy beam of electrons. As the electrons interact with the sample, they produce secondary electrons, backscattered electrons, and characteristic X-rays. These signals are collected by one or more detectors to form images which are then displayed on the ... WebScanning electron microscopy works by scanning a sample with electron beams. An electron gun fires these beams, which then accelerate down the column of the scanning …
