A microscope is used to magnify small objects. Microscopes are often used in scientific or educational settings to observe objects and living organisms that wouldn’t be visible to the naked eye. It is important to learn about the different parts of a microscope to understand how these devices work.

With Labeled Diagram and Functions
How does a Compound Microscope Work?
Before exploring the parts of a compound microscope, you should probably understand that the compound light microscope is more complicated than just a microscope with more than one lens.
First, the purpose of a microscope is to magnify a small object or to magnify the fine details of a larger object in order to examine minute specimens that cannot be seen by the naked eye.
Here are the important compound microscope parts...
anatomy of a microscope
Eyepiece: The lens the viewer looks through to see the specimen. The eyepiece usually contains a 10X or 15X power lens.
Diopter Adjustment: Useful as a means to change focus on one eyepiece so as to correct for any difference in vision between your two eyes.
Body tube (Head): The body tube connects the eyepiece to the objective lenses.
Arm: The arm connects the body tube to the base of the microscope.
Coarse adjustment: Brings the specimen into general focus.
Fine adjustment: Fine tunes the focus and increases the detail of the specimen.
Nosepiece: A rotating turret that houses the objective lenses. The viewer spins the nosepiece to select different objective lenses.
Objective lenses: One of the most important parts of a compound microscope, as they are the lenses closest to the specimen.
A standard microscope has three, four, or five objective lenses that range in power from 4X to 100X. When focusing the microscope, be careful that the objective lens doesn’t touch the slide, as it could break the slide and destroy the specimen.
Specimen or slide: The specimen is the object being examined. Most specimens are mounted on slides, flat rectangles of thin glass.
The specimen is placed on the glass and a cover slip is placed over the specimen. This allows the slide to be easily inserted or removed from the microscope. It also allows the specimen to be labeled, transported, and stored without damage.
Eyepiece: The eyepieces are the lenses at the top that the viewer looks through; they are usually 10X or 15X. To get the total magnification level, multiply the magnification of the objective used (ex: 10X eyepiece * 40X objective = 400X total magnification).
Tube: Where the eyepieces are dropped in. Also, they connect the eyepieces to the objective lenses.
Base: The bottom of the microscope—what the microscope stands on.
Arm: Structural element that connects the head of the microscope to the base.
Stage: The flat platform that supports the slides. Stage clips hold the slides in place. If your microscope has a mechanical stage, the slide is controlled by turning two knobs instead of having to move it manually. One knob moves the slide left and right, the other moves it forward and backward.
Illuminator: A steady light source (110 volts in the US) that shines up through the slide. Mirrors are sometimes used in lieu of a built-in light. If your microscope has a mirror, it is used to reflect light from an external light source up through the bottom of the stage.
Nosepiece: This circular structure is where the different objective lenses are screwed in. To change the magnification power, simply rotate the turret.
Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. The most common ones are 4X (shortest lens), 10X, 40X and 100X (longest lens). The higher power objectives (starting from 40x) are spring loaded. Spring loaded objective lenses will retract if the objective lens hits a slide, preventing damage to both the lens and the slide. All quality microscopes have achromatic, parcentered, parfocal lenses. In addition, to get the greatest clarity at high levels of magnification, you will need a microscope with an Abbe condenser. Lenses are color coded and are interchangeable between microscopes if built to DIN standards.
Rack Stop: This feature determines how far up the stage can go. Setting the rack stop is useful in preventing the slide from coming too far up and hitting the objective lens. Normally, this adjustment is set at the factory, and changing the rack stop is only necessary if your slides are exceptionally thin and you are unable to focus the specimen at higher powers.
Consender lences: Condenser lenses focus the light that shines up through the slide, and are useful for attaining sharp images at magnifications of 400X and above. If the maximum power of your microscope is 400X, a stage mounted 0.65 NA (or greater) condenser is ideal since it give you greater clarity without having to be focused separately. However, if your microscope goes to 1000X or above, focusable condenser lens with an N.A. of 1.25 or greater is needed. Most microscopes that go up to 1000X come equipped with an Abbe condenser, which can be focused by moving it up and down. The Abbe condenser should be set closest to the slide at 1000X, and moved further away as the magnification level gets lower.
Diaphragm or Iris: The diaphragm or iris is located under the stage and is an apparatus that can be adjusted to vary the intensity, and size, of the cone of light that is projected through the slide. As there is no set rule on which setting to use for a particular power, the setting depends on the transparency of the specimen and the degree of contrast you desire in your image.

Microscopes are instruments that are used in science laboratories, to visualize very minute objects such as cells, microorganisms, giving a contrasting image, that is magnified. Microscopes are made up of lenses for magnification, each with their own magnification powers.
Eyepiece – also known as the ocular. this is the part used to look through the microscope. Its found at the top of the microscope. Its standard magnification is 10x with an optional eyepiece having magnifications from 5X – 30X.

So that you know how to use it and when to use it
So we can use it properly and to know how will we use it.
