WebBecause of the geometry of the imaging system, scanning electron microscopes have a much greater depth of field than optical microscopes, where the whole specimen can be in focus. This is because, for the optical microscope, the depth of focus is the distance above and below the image plane over which the image appears in focus. WebFixation and dehydration are important for preparing samples for both the TEM and the SEM. However, other aspects of sample preparation differ greatly because the two microscopes have different requirements. For TEM, samples must be cut into very thin cross-sections. This is to allow electrons to pass right through the sample.
