The uses of a microscope are very significant in scientific studies and in other fields. A microscope is used to view things that are too tiny to be seen by the naked eye or to blow up the visual size of an item. A microscope lab may be found in a police precinct, a forensic lab or a school laboratory.
Uses of a Microscope
The list below details the uses of a microscope in various fields and how one is used:
The uses of a microscope will depend on the type of microscope being used. A microscope lab can contain electron microscopes, fluorescent microscopes and light microscopes. Nonetheless, the basic functioning of a microscope is the same across the board.
Mechanism of a Microscope
The microscope functions by use of lenses to expand the specimen under it. The basic technology is the use of lenses to magnify the object. Artificial or natural light is used to aid in the magnification. The light source ought to be very bright in order to aid the visualization.
The microscope generally consists of the following sections:
With advances in technology, the uses of microscopes can only be more and more advanced.
A microscope is an optical instrument used to look at objects that cannot be seen by the naked human eye. From its invention, the microscope has had many uses that include tissue examinations and forensic examination. It is because of its many uses that the microscope is a permanent fixture in most kinds of labs whether medical or scientific. To understand the uses of the microscope, a person needs to know all the different parts of the microscope.
Types of a Microscope
There are numerous types of microscopes in the market that include. The oldest type of microscope, which is the optical microscope, uses light to generate and view specimen, and the electron microscope that uses electrons for specimen illumination. The following are parts of a microscope.
Parts of the Optical Microscope
One has to start from the basics to be able to understand the various parts of a microscope. Understanding the parts of the optical microscope and its microscope lab activities can help know how the other microscopes work.
Objective Lens: This can either have three or four lens. These lenses include the low power objective used to look at large specimen and also to get an overview of the specimen. The second most important objective lens is the high power objective part of the microscope, which gives you a much detailed view of any small specimen. The objective lenses are usually attached to the revolving turret or nosepiece.

Microscopes are inventions that have opened the world of microbes and minuscule objects which paved the way for the discovery of causative agents of numerous deadly diseases. Microscopes are indeed one of the biggest and most revolutionary inventions until now. A microscope is a device that has the ability to magnify an object. Objects are magnified hundred fold, thousand fold and so on so that they can be seen with the naked eye with ease. Different types of microscopes are highly useful in biological labs to study cells, tissues, bacteria and other microorganisms.
Depending on the principle of how they work, there are various types of microscopes available. The magnifying power varies and the functioning differs from one microscope to the other. Here is a broad classification of the various types of microscopes and their uses:
Types of Microscopes
There are simple microscopes and compound microscopes in the basic classification where simple microscopes have only one lens and are used to magnify fairly larger objects while compound microscopes have two lenses and have greater magnifying power. Simple microscopes are also known as dissecting microscopes because they are used for dissections.
Microscopes are again divided into light microscopes and electron microscopes depending on the source used for magnification.
Light microscopes utilize light for illumination and may be of various types again.
Their usage varies and adjustments may be done accordingly. Bright field microscopes are the most common microscopes used in labs. Fluorescent microscopes use fluorescent light. Phase contrast on the other hand are types of microscopes that make the magnified image of the object visible through a sharp contrast and dark field microscopes illuminate the background instead of the image itself.
These are more sensitive and have a larger magnifying power than light microscopes. These microscopes do not use light but electrons and thus need to be handled with a lot of care. They are classified into:
The latter uses a single beam of light and magnifies even the smallest details of cells. The SEM provides a three dimensional image and the accuracy is the biggest advantage of electron microscopes. There are more numerous variations on the types of microscopes such as the tunnelling microscope which also uses electrons. This is again a very sensitive microscope that uses high-end technology.
Depending on the requirement and purpose of the microscope lab, you can choose from the wide array of microscopes available. Whether you are a hobbyist or a professional, it is important for you to buy the right brand and to check everything before purchase so that you don’t end up buying the wrong type of microscopes. Cheap microscopes will not give you the accurate magnification and your experiments can go wrong.
A microscope laboratory or microscope lab teaches about the microscope in a school setting. The microscope is an instrument that is used in many fields. It helps to study small minute objects by enlarging them. The most common microscopes used are compound microscopes. They have two lenses to help enlarge the object that you view through them. The objective of a microscope lab is to teach about the microscope and how to use it.

Not only do you learn how to use this instrument and its various parts and their functions but you also learn how to handle the instrument during this laboratory activity. Though you get to learn about the microscope in a microscope lab, there may be times when you do not get enough time with the instrument to be able to understand everything that is being taught. With the internet also being a tool of learning, there are sites on the web which are dedicated to online microscope lab. Here you will find information that you may have been unable to pick up when learning about the microscope in school.
There is also a virtual microscope lab on the internet where you can get to see images of different specimens as you would see them under the microscope. These labs are very informative and give information and visuals that you may not be able to see because of constraints of cost and time. Though these labs are not a substitute for the real hands on experience, they do let you get familiarized with the microscope and prepare you for the actual use.
The Compound Microscope
Compound microscopes are used in many fields where there is a need for high magnification of very small subjects. Though more often you will find the microscope being used in various laboratories like biology, botany, geology, genetics and many more.
This microscope is also used in forensics and by scientists in studying minute details of samples. It plays an important role in helping law enforcement technicians study evidence and help them catch the criminals.
In today’s world, microscopes play an important part not only as educational tools in schools and colleges but as instruments that have helped develop the scientific field through many discoveries found in the tiny samples that they help magnify.
Microscope lab is a useful learning tool where the students get to actually handle the microscope and learn how to use it. Without the microscope lab, it would be difficult to use a microscope in higher learning and you would have to first learn the microscope before using it for examining specimens. A microscope lab not only teaches students how the microscope works and how it has to be used, but you are also taught how to handle the instrument so that you do not damage it or break it while using it. So be sure that you pay attention during your laboratory activitie because you might need the use of a micsoscope someday.
