Parts of a Microscope

Microscope Parts and their Functions –

A microscope is used by geologists to study micro – organisms in sand, used by any veterinarian as a tool which helps to treat the health of animals. We know how a microscope looks like. let us know some parts of a microscope –

1. Eye – Piece or Ocular Lens –

It is a magnifying glass which is attached to a microscope and so it is known as eye – piece and is placed near the eye where we see the image from.

2. Body Tube –

A body tube is an internal part of microscope which holds the eye – piece and is connected to the objective.

3. Arm –

The arm is a part of microscope which connects the base and to carry the microscope from one place to another place. The arm must be made with a good material as we use it to carry the microscope.

4. Base –

The base is the bottom part of the microscope which is also made of durable material as it supports the whole microscope. The base is very important as it must provide stability to get accurate results.

5. Illuminator –

An illuminator is a source of light ( low voltage halogen bulb ) which is present at the bottom near the base of the microscope.

6. Stage –

A Stage is a place where the specimen is placed for examination. It is an indispensable part of a microscope and is a flat surface used for higher magnifications.

7. Stage Clip –

Stage clips are holding devices for slides when there is an absence of mechanical stage. The movement of slides is very crucial and provides stability for the slides.

8. Turret –

A Turret is also known as Turret and is a part of a microscope which helps to hold two or more pieces simultaneously.

9. Objective Lens –

Objective Lens is a part of microscope which helps to magnify the image of a specimen. There are usually three types of objective lens and a standard microscopes are 10X, 40X and 100X.

10. Rack Stop –

Rack Stop is a part of a microscope which is responsible for determining and adjusting the distance between the object and the object lens.

11. Condenser Lens –

Condenser Lens is a part of a microscope and is used to collect the light from the illuminator and it helps to focus light on the specimen placed on the stage.

12. Diaphragm –

The Diaphragm is also a part of the microscope and is used to control the amount of light reaching the specimen. It is a rotating disc above the condenser and under the stage. There are various holes to facilitate the experiments.

13. Coarse Adjustment Knob –

Coarse Adjustment Knob is a knob which is present at the arm of the microscope and its main function is to move the specimen back or forth and helps to focus the light show the best image as possible.

14. Fine Adjustment Knob –

The knob helps to make the specimen focus sharply and is a sub – part of Coarse Adjustment Knob.

15. Power Switch –

A power switch is also a part of a microscope and is an electrical switch which is present at the bottom of the microscope. This helps to switch the light source, i.e., the illuminator.

16. Low Power Object –

Low Power Object avoids ramming into the slide and protects it from breaking. It is mostly used in microscopes to view slides.

17. High Power Objective –

High Power objective is also known as high dry objective and is used to study the specimens placed on the stage. It has a bit higher power when compared to Low Power Object and must be handled with care.

18. Specimen on the Glass Slide –

The glass slide dimensions will be 75 X 26 mm and about 1 mm thick. The specimen will be kept on this glass slide.

19. Aperture –

Aperture is a small hole through which light will be transmitted and passed on to the slide.

These are the major parts of a microscope.
