The electron microscope is a type of microscope that uses electrons to enlarge and illuminate an image of a specimen.
Transmission: A beam of electrons pass a sample and is absorbed in electron-dense structures, which look black in an image. Scanning: samples are coated with metal and scanned with a beam of electrons.
Scanning electron microscope (SEM)
Depth of field in a microscope refers to the distance between the nearest and the furthest objects that produce a distinct image of a specimen. It is usually very short and is measured in microns.
The speciman you are viewing must be in a vacuum, and be coated with a metal film, therefore the specimen can't be alive and if its a Transmission Microscope- Speciman must be extrememly thin so that the electrons can pass through them. The image is black and white.
An Electron Microscope uses electrons to magnify objects.
Transmission Electron Microscope is used to take an image of a cell and split it and get information from the inside of the cell
electrons passing through ultra thin samples of cells or tissues
It can produce images of objects within a cell.

The Transmission Electron Microscope (TEM) was the first type of Electron Microscope to be developed and is patterned exactly on the Light Transmission Microscope except that a focused beam of electrons is used instead of light to "see through" the specimen. It was developed by Max Knoll and Ernst Ruska in Germany in 1931.The first Scanning Electron Microscope (SEM) debuted in 1942 with the first commercial instruments around 1965. Its late development was due to the electronics involved in "scanning" the beam of electrons across the sample. TEM focus a beam of electrons through a specimen while SEM focus a beam of electrons onto the surface of a specimen and the image provided is 3-Dthe transmission microscope magnifies 300,000 more times and the scanning microscope only magnifies 100,000 more the transmission gives the image of the inside and the scanning microscope gives a 3D image of the surface of the specimen

Actually, the image doesn't form in the microscope. The image forms on your retinas. The microscope focuses light in such a way that it comes together correctly on your retinas.
It is black and white.
There there are many. Simple microscope, compound microscope, light microscope, scanning electron microscope, TEMicroscope, Dissection microscope, etc and most of them are used to see small cells that cannot be seen by the naked eye.
