The document describes the main parts of a microscope and their functions. The eyepiece is used to view the slide and usually has a magnification of 10x. The fine and course adjustments control focus, with the fine adjustment used for small changes and the course adjustment for larger movements. The stage holds the slide and the stage clips secure it in place. The objective lenses provide different magnifications and the nosepiece allows rotation between them. The mirror, body tube, arm, base, and diaphragm also have specific microscope functions.

3. Eyepiece
• The eyepiece is the part of the microscope which you look through.
• It usually has its own magnification of 10x.
eyepiece

4. Fine Adjustment
• This part of the microscope is used when changing small amounts of focus.
Fine adjustment

5. Course Adjustment
• Used when making large changes in focus on the microscope
Course Adjustment
• Moves the body tube up and down

6. Adjustment
• Some microscopes only have ONE adjustment knob
• If so, it is a course adjustment!

7. Stage
• Where slides are placed on the microscope for viewing.
Stage

8. Mirror
• The mirror is used to reflect light from a light source up through the diaphragm
Mirror

9. Body Tube
• The body tube holds the eyepiece of a microscope and connects it to the objectives
Body Tube

10. Objective
• The magnifying lens, comes in different powers

11. Stage Clips
• The stage clips hold the slide in place

12. Arm
• The arm is used for safe transportation of the microscope

13. Base
• What the microscope uses to “sit” on, also used for safe transportation
Base

14. Nosepiece
• The nosepiece holds two or more objective lenses and can be rotated to easily change
powers

15. Diaphragm
• Used to vary the amount of light which passes through the slide
• Usually better in lower amounts
