The Different Parts Of A Compound Light Microscope
The invention of a compound light microscope has been crucial in the quest of a deeper understanding of human kind, their origin, structure, and everything else around it. Know how compound light microscopes work by specifying its different components.
Understanding how microscopes functions starts by analyzing its different parts and defining their purpose while in the process. Uncover the marvel that’s inside each microscope. Here are the important parts of a compound light microscope that primarily allows it to do its job:
1. Eye piece lens. The eyepiece lens of a compound light microscope is found at the uppermost part of the device. This is where you peep into to get a good view of the specimen under observation. An eye piece lens is usually has a10x or 15x magnification power. Some microscopes have a single eye piece. These are the monocular types. There are those that have dual eye piece. These are called the binocular microscope. The more complex microscope in terms of the number of eye pieces would be trinocular microscopes. These ones have three eye piece ports. The additional port is commonly used to attach a video or still imaging camera into.
2. Tube. The microscope’s tube is the main part that connects the eye piece into the set of objective lenses. The tube is usually a few diameters thicker than the eye piece. It is made of metal or hard plastic, depending upon what the body of the entire microscope is made of. Tube.

3. Arm. The arm is a part of the microscope’s body as well. It is the one that supports the eye piece, the tube, and the objective lenses. It is also the same on that connects them all to the base. It can also serve as a handle so that users can carry the microscope and transfer it to another location.
4. Base. The base is the bottom of the microscope. Its main purpose is to support the whole system and keep them together. One end of the arm is connected to the base, which in turn, is the part where the stage is attached.
5. Illuminator. The illuminator is the microscope’s light system. Usually, it is powered with 110 volts and is transmitted to the stage up until the light reaches the eye piece using a mirror. Microscopes with mirrors have external light sources and use the process of reflection to illuminate the specimen for proper viewing. Halogen lights and fluorescent lights are the most commonly used external light sources for compound light microscopes.
6. Stage. The stage is where you put your specimens into. It is in the stage is where you put your slide in. The stage also have clips that hold these slides into place. There are compound light microscopes that have mechanical stages. A mechanical stage can be moved and manipulated as desired.
7. Objective lenses. A compound light microscope has round three to four objective lenses attached to it. If the microscope only has a single objective lens, then it cannot be called a compound microscope. The objective lenses have different magnification levels and the lowest one is around 4x. The power of the lenses varies from 10x all the way up to 1000x for superior magnification capability.
8. Condenser lens. The condenser lens is used to focus light into the specimen. These lenses are very useful if high objective lenses are used. It provides the users with sharper images. More often than not, these condenser lenses are placed in the stage for it to function well. Condenser lenses can be moved accordingly so that better image viewing is achieved.
9. Diaphragm. The microscope’s diaphragm is the rotating disk found under the microscope’s stage. It contains holes in different sizes so that the intensity, as well as the size of the light’s cone can be controlled. Users can move the diaphragm depending upon what suits them best.
10. Rack stop. The rack stop is a type of adjustment tool that determines the ability of the objective lens to get close to the slide. More often than not for compound light microscope, it is pre-set at the factory level so that novice users can’t adjust it breaking the objective lenses in the process.
These are the different parts of a compound light microscope. Each of these components works hand in hand in order to produce powerful magnification of small specimens such as bacteria, viruses, cells, and other minute substances.
