Fibers, a fly's eye, a close up of Gun shot residue (link to EDX for elemental breakdown) etc. small things!
An Electron Microscope is used to study the contents of a nucleus.

A comparison microscope is commonly used to see fingerprints. This type of microscope allows two objects (such as two fingerprint samples) to be viewed side by side, making it easier to analyze their similarities and differences.
An electron microscope is needed to view viruses because viruses are much smaller than bacteria and cannot be seen with a light microscope. Electron microscopes use a beam of electrons to magnify the image, allowing for higher resolution and the ability to see smaller structures such as viruses.
Ribosomes are too small to be resolved by a scanning electron microscope, which typically has a lower resolution limit of 1 nanometer. Ribosomes are only about 20-30 nanometers in size, making them beyond the detection capabilities of this kind of microscope. Transmission electron microscopes, with much higher resolution capabilities, are used to visualize ribosomes.

Really small things. Because there are limits to how small an object we can observe through a light microscope, we developed the electron microscope. By setting up a sample and streaming electrons at it to resolve an image, we can "see" things smaller than we'd be able to see through a light microscope.
You would use an electron microscope to view a Golgi apparatus.

Scanning electron microscope (SEM) is the kind of microscope where the specimen is coated with a thin film of a heavy metal like gold and then observed using an electron beam that is directed down on it.
Scientists would use an electron microscope when a light microscope isn't strong enough. Electron microscopes use a beam of electrons rather than light to achieve much higher magnification and resolution, allowing for the visualization of smaller details in samples.
To see a virus, a Transmission Electron Microscope (TEM) or a Scanning Electron Microscope (SEM) would be better than a compound light microscope. TEM uses a beam of electrons to create an image with high resolution and can visualize viral structures inside cells. SEM provides detailed 3D images of virus surface morphology at a higher magnification than a compound light microscope.
