syed514. There are three types of microscope with the ability to produce three-dimensional images. The scanning electron microscope (SEM) and transmission electron microscope (TEM) both use beams of electrons to produce an image of the sample. Theconfocal laser scanning microscope uses a laser beam to produce an image ...
