Question

What are some similarities and differences between SEM and TEM microscopes

Answer 1

SEM and TEM are electron microscopes whereas the SEM uses reflected electrons and TEM uses transmitted electrons to form an image

Explanation:

• SEM is the scanning electron microscopes and TEM is the Transmission electron microscope

• SEM works by detecting the scattered electrons to create an image of the sample whereas the TEM detects the transmitted electrons to create the image of the sample

• SEM will only be analysing the surface of the sample whereas TEM collects data vertically also

• TEM sample needs to cut thinner than SEM and TEM will give high-resolution images than SEM
