Transmission electron microscopes function by generating, aiming and focusing a beam of electrons onto the surface of a subject, providing a highly magnified image for the operator. The electron beam is focused using magnets in a similar manner as that in which light beams are focused using lenses, and is then directed to the subject within the microscope’s sample chamber. The sample chamber prevents the subject from being jostled or moved, which would have a severe effect on the scan because of the high level of magnification. Scientific Research The superior magnification of transmission electron microscopes has allowed researchers to observe the world, test existing theories and discover new laws go
