An electron microscope can only operate inside a vacuum chamber. A good vacuum, needed so that electrons do not collide with air molecules or dirt before reaching the sample and the detector coming back, would be 1e-7 Torr or below. Your sample (the object of interest) has to be small enough to be mounted on a pedestal, which is inserted into chamber where the electron beam will be. The pedestal has to have multiple degrees of freedom so the e-beam can interrogate at various angle and position. The last requirement would be that your sample does not charge up too easily, which will distort the image. Charging can be lessened with a flash of gold.
Hence, if your sample meets the requirements listed, you should be able to see its image on a monitor just as clearly as you see an object of a much larger scale, with an optical microscope. Any items that are detrimental to a vacuum formation (moist, spongy materials, for example) should probably be avoided. From an electron microscope, I have seen something as big as the compound eyes of a fly or a feature as small as 1 nm.
An electron microscope can reveal details at the nanometer scale, showing very fine details of objects such as cells, bacteria, viruses, and materials. It provides high-resolution images allowing scientists to see the internal structure of these specimens in great detail.

What can be seen under a transmission electron microscope?
Under a transmission electron microscope, one can see the internal structure of cells, tissues, and individual molecules at a very high magnification. This type of microscope can reveal details such as the arrangement of atoms and the ultrastructure of organelles within cells.
Why are individual cells not visible under an electron microscope?
Individual cells are not visible under an electron microscope because the resolution of the microscope is not high enough to distinguish the borders of individual cells. The electron microscope's resolution is limited by the wavelength of electrons used, preventing the visualization of single cells. Cells can be seen collectively as tissues or structures under an electron microscope.
What is the minimum size of the organism which could be seen under microscope?
The minimum size of an organism that can be seen under a light microscope is around 0.2 micrometers, which is the limit of resolution for this type of microscope. Anything smaller than that would require an electron microscope for visualization.
Which type of microscope allows you to see inside the cell (organelles) 3D images or bacteria?
An electron microscope, particularly a transmission electron microscope (TEM), allows you to see inside the cell and view organelles in detail. It provides high magnification and resolution to observe the internal structures of cells. However, bacteria can also be visualized using a light microscope or a scanning electron microscope (SEM).
What microscope would you need to see the details inside a bacterium?
You would typically need an electron microscope to see the details inside a bacterium, as the resolution of an electron microscope is much higher than that of a light microscope. Electron microscopes use a beam of electrons to create an image, allowing for detailed visualization of the internal structures of bacteria.
Can really be an electron seen under microscope?

What can be seen under a electron microscope and not a light microscope?
Under an electron microscope, structures can be seen with much higher resolution compared to a light microscope. This includes viewing individual molecules, detailed cell structures, and even viruses. The high magnification and resolution of an electron microscope allow for visualization of fine details that are not visible under a light microscope.
What type of microscope would you need to see detailed images of an internal structure of a bacterium a light microscope or an electron microscope?
An electron microscope would be needed to see detailed images of an internal structure of a bacterium, as it can provide much higher magnification and resolution compared to a light microscope. The electron microscope uses a beam of electrons instead of light to visualize the specimen, allowing for better visualization of internal structures at the cellular level.
What can be seen under a electron microscope but not a light microscope?
Subcellular structures like ribosomes, protein complexes, and viruses can be seen under an electron microscope due to its higher magnification and resolution capabilities compared to a light microscope. The electron microscope uses a beam of electrons to create an image, providing much finer details than a light microscope that uses visible light.
What microscope lets you see individual atoms?
electron tunneling microscope
What microscope is best to see moving amoeba?
A Transmission Electron Microscope
What is the differences between a compound and electron microscope?
The compound microscope is a light microscope that uses light to "see" microbes. Viruses are too small.The electron microscope uses electrons to "see" microbes or viruses.
What part of an atom is visible under the microscope?
A single atom is not visible in a microscope (it is too small to be imaged by photons). What you see in an optical microscope (or in general) is the light reflected, scattered, or emitted by the electron layers of the material under observation.
What do you nee to see a virus?
