That light reflects from the sample and is captured, focused, and magnified by lenses. Optical Microscope (left) vs Scanning Electron Microscope (right). greek the showWebThe 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 flower delivery santo domingo

"WebIn a TEM microscope, the sample is located in the middle of the column. The transmitted electrons pass through it and through a series of lenses below the sample (intermediate and projector lenses). An image is directly shown on a fluorescent screen or via a charge-coupled device (CCD) camera onto a PC screen. " - How does a tem microscope work
