optical microscope
This type of microscope is called a light microscope. Because it uses visible light to detect and magnify small objects, and it is the most well-known research tool in the field of biology, and its cost varies according to its quality and versatility, and it is used by students and teachers, and the least expensive microscopes enable students to conduct some rather complex experiments, and help in Recognize some types of the smallest organisms; Like bacteria, the shape of the cell can also be recognized when magnified by 100×.
The compound microscope is the most common microscope of the light microscope, and it is characterized by its containing an eyepiece that magnifies the body ten times, in addition to four secondary lenses capable of magnifying the body ten, forty, or a hundred times, where the sample is placed on a base the microscope, and the light passes through it to the objective secondary lens, then to the eye lens; To magnify the object twice, the light compound microscope can enlarge the object about a thousand times.
Electron microscope
An electron microscope (in English: Electron microscope) is a type of microscope that uses electrons to see the sample, and some electron microscopes can magnify samples two million times, and some biological samples need to be coated with a very thin layer of metal before being studied through it, and this type of microscope is used by Researchers in several fields, including: physical, medical, biological, mineralogy, nanotechnology, forensic analysis, examining samples from insects to bones, and there are two types of electron microscopes:

- Scanning electron microscopeScanning Electron Microscope: Where the electrons in this microscope bounce off the sample and do not pass through it, to see the surface structure of the sample and form a three-dimensional image of it.
stereoscopic microscope
A stereoscope uses visible light to magnify, and is characterized by providing a three-dimensional image of objects, and is used to obtain a better image of large samples; Where it is easy to deal with it, and enlarge it without preparing a slide, and it can enlarge objects three hundred times, and this type of microscope is used in several fields; Such as applications in the biological and medical sciences, and in the electronics industry, such as: making watches, or manufacturing circuit boards.
