    Both types of EM use some sort of metal coating, therefore how do you explain that one type (transmission) produces a two dimensional image and the other type (scanning) produces a three dimensional image?

    1. Both types of EM use some sort of metal coating, therefore how do you explain that one type (transmission) produces a two dimensional image and the other type (scanning) produces a three dimensional image."

    Transmission electron microscope (TEM): In the TEM, an electron beam is passed through a very thin (~0.1 micrometres) specimen and the "image" is detected on a phosphorescent screen or on photographic film. In order to achieve such thin ...

    Solution Summary

    Since both types of EM uses some sort of metal coating, this solution explains how it is that one type (transmission) produces a two dimensional image and the other type (scanning) produces a three dimensional image.
