What's the difference between SEM and TEM microscopes?
A SEM (scanning electron microscope) images using the electrons reflected from a specimen. A TEM (transmission electron microscope) images using the electrons that pass through it.
The image from an SEM thus looks somewhat like a normal photo (we're used to imaging using the light reflected from objects). However, a TEM image takes a bit more interpretation as we're not used to seeing images of light that's passed through things - think of silhouettes or slide projectors…
