Step-by-step solution for: Parts of a Microscope with Their Functions • Microbe Online
It looks like you've uploaded a Microscope Parts Worksheet with a labeled compound microscope diagram. The goal of this worksheet is likely to identify the parts of the microscope based on their numbers.
Below is a complete identification of each numbered part, along with a brief explanation of its function:
---
1. Eyepiece (Ocular Lens)
– The lens you look through to view the specimen. Often has a magnification power (e.g., 10x).
2. Head (Body Tube)
– Connects the eyepiece to the objective lenses and maintains proper alignment.
3. Arm
– The structure that connects the head to the base; used to carry the microscope.
4. Coarse Adjustment Knob
– Large knob used to raise or lower the stage quickly for initial focusing.
5. Fine Adjustment Knob
– Smaller knob used for precise focusing after coarse adjustment.
6. Stage Clips
– Hold the slide in place on the stage.
7. Stage
– Platform where the slide is placed for viewing.
8. Diaphragm (Iris Diaphragm)
– Controls the amount of light passing through the specimen.
9. Condenser
– Focuses light onto the specimen (often below the stage).
10. Nosepiece (Revolver)
– Rotating part that holds the objective lenses.
11. Base
– Bottom support of the microscope; houses the light source.
12. Light Source (Illuminator)
– Provides light to illuminate the specimen (usually LED or bulb).
13. On/Off Switch
– Turns the light source on or off.
14. Objective Lenses
– Lenses mounted on the nosepiece; provide different magnifications (e.g., 4x, 10x, 40x, 100x).
15. Rack Stop
– Prevents the stage from moving too far up and crashing into the objectives.
16. Stage Aperture
– Opening in the stage through which light passes.
17. Mechanical Stage
– Allows precise movement of the slide using controls.
18. Specimen Slide
– Glass slide containing the sample to be viewed.
19. Focus Adjustment Knob (for mechanical stage)
– Controls lateral movement of the stage.
20. Objective Lens Holder
– Part of the nosepiece that holds the objective lenses.
21. Binocular Head
– Dual eyepieces for comfortable viewing with both eyes.
22. Interpupillary Distance Adjustment
– Adjusts the distance between the two eyepieces to match your eye spacing.

- Match each number to the correct part name.
- Practice labeling the parts without looking at the key.
- Understand the function of each part — knowing what it does helps remember the name.
