1. Compound Microscope:

2. The Compound Microscope:
The Compound Microscope is the most commonly used microscope.
It allows you to see things that can not be seen with the naked eye.

3. Eyepiece: The first lens at the top of the microscope (monocular).
Numbers near the eyepiece refer to total magnification of the lens.
Usually has a magnification of 10x.
Example: 10x = ten times larger than normal.

4. Body Tube:
Extends below the eyepiece.
Helps in focusing the lenses.

5. Revolving Nosepiece: At the end of the body tube.
Where the objectives are attached.
Allows the observer to change from low power to high power.

6. Objectives:
The low and high power lenses.

7. Low Power Objective: The shortest of the objectives.
Usually has a magnification of 4x.

8. Medium Power Objective:
Intermediate in length.
Usually has a magnification of 10x.

9. High Power Objective: The longest of the objectives.
Usually has a magnification of 40x.

10. Stage:
Supports the slide.

11. Stage Clips:
Connected to the stage.
Secures the slide.

12. Diaphragm:
Regulates the amount of light entering the microscope.

13. Coarse Adjustment: Brings objects into rapid but approximate focus.
Used for initial focusing (first).

14. Fine Adjustment: Brings objects into a more exact focus.
Used for final focusing (second).

15. Lamp:
Electrical light source.

16. Arm: Holds the top portion of the microscope.
Should be held during transport.

17. Base: Bottom part of the microscope.
Should also be held during transport.
