Question

what is difference between size of scanning electron microscope and transmission electron microscope​

Answer 1

Explanation:

TEM users can magnify their samples by more than 50 million times, while for the SEM, this is limited to 1–2 million times. However, the maximum field of view (FOV) that SEMs can achieve is far larger than TEMs, meaning TEM users can only image a very small part of their sample.

Answer 2

The main difference between SEM and TEM is that SEM creates an image by detecting reflected or knocked-off electrons, while TEM uses transmitted electrons (electrons that are passing through the sample) to create an image.
