The SEM microscope uses a high-energy beam of electrons that interact with the atoms that make up the sample producing signals that contain information about the sample's surface topography, composition and other properties such as electrical conductivity.
There are at least two types of microscope that can give 3D images. Confocal microscopes that use lasers to illuminate the object and scanning electron microcopes (SEM) that use an electron beam. A SEM can give better magnification than confocal but confocal can image live moving subjects. In SEM the object of intrest must be coated with gold so only dead things can be imaged.
When you use a microscope it will magnify the object you are looking at.Unwanted publicity can magnify the effect of a small political indiscretion.
You would use a scanning electron microscope (SEM) to examine thick objects that do not allow light to pass through them. SEM uses electron beams instead of light to create detailed images of the surface of the object.
yes
Electron microscopes, specifically transmission electron microscopes (TEM) and scanning electron microscopes (SEM), are capable of achieving magnifications up to 100,000 times. These microscopes use a beam of electrons instead of light to magnify the specimen, allowing for much higher magnification levels compared to light microscopes.
TEM (transmission electron microscope) and SEM (scanning electron microscope) use electron beams instead of light to magnify specimens, providing higher resolution images. Compound microscopes use visible light and lenses to magnify specimens. TEMs transmit electrons through the specimen to create an image, while SEMs scan the specimen's surface with electrons to generate an image.
The scanning electron microscope uses a focused beam of electrons to magnify images. This beam scans the surface of the specimen, and the interaction between the electrons and the specimen produces signals that are used to create a detailed image.
An electron microscope can enlarge images up to 1500 times. These microscopes use a beam of electrons to magnify objects to a very high resolution, allowing for detailed examination of tiny structures.
A scanning electron microscope (SEM) can achieve magnifications of up to 27,900x or even higher, depending on the model and conditions. SEMs use focused beams of electrons to create detailed images of the surface topography and composition of specimens. This high level of magnification allows for the observation of fine details at the nanoscale.

microscopes use the lens
A electron microscope uses beams of highly charged, energetic, electrons, due to these electrons this type of microscope can magnify the object it is looking at by two thousand times! So because we can magnify an object by such a great amount we can use electron microscopes to observe how atoms are arranged in an object and even look at the structure of an atom.
You can magnify microscoptic things with a microscope.
We would normally use a microscope to do this.

An electron microscope uses a beam of electrons instead of light to magnify specimens. This allows for higher resolution images and the ability to view smaller details compared to light microscopes.
When you want to look at things you couldn't with a light microscope.
