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
They all use lenses to magnify images. Lenses are able to bend light rays in a way that makes objects appear larger when viewed through the lens.
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.

microscopes use the lens
You can magnify microscoptic things with a microscope.
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.
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.
You would use a scanning electron microscope (SEM) to observe the surface features of a bacterium. SEM provides high-resolution images of the specimen's surface by scanning it with a focused beam of electrons. This allows for detailed visualization of the bacterium's structure at a nanoscale level.
