Let's solve the
"Parts of a Microscope Worksheet" by identifying each labeled part of the microscope in the diagram.
Here is the correct identification for each numbered part:
---
1. Eyepiece (Ocular Lens)
- This is the lens at the top of the microscope that you look into. It magnifies the image produced by the objective lenses.
2. Revolving Nosepiece (Turret)
- The rotating part that holds the objective lenses. You can switch between different magnifications by turning it.
3. Objective Lenses
- These are the lenses located below the nosepiece. They come in different magnifications (e.g., 4x, 10x, 40x, 100x). They gather light from the specimen and produce a magnified image.
4. Stage
- The flat platform where the slide is placed for viewing. It often has clips to hold the slide in place.
5. Stage Clips
- Small metal clips on the stage that hold the glass slide securely in place.
6. Diaphragm (Iris Diaphragm)
- Located beneath the stage, it controls the amount of light that passes through the specimen. It helps adjust contrast and brightness.
7. Light Source (Illuminator)
- The light at the base of the microscope that provides illumination for the specimen. In older models, this may be a mirror reflecting light from an external source.
8. Arm
- The curved support that connects the head (eyepiece) to the base. It’s used to carry the microscope.
9. Base
- The bottom part of the microscope that supports the entire structure and houses the light source.
10. Coarse Adjustment Knob
- The larger knob used to move the stage up and down rapidly for initial focusing.
11. Fine Adjustment Knob
- The smaller knob used for precise focusing after coarse adjustment. It makes small movements to sharpen the image.
12. Mirror (or Reflector)
- In some microscopes, especially older ones, a mirror reflects light upward through the specimen. In modern microscopes, this is replaced by a built-in light source.

📌 Notes:
- Modern compound microscopes typically have an electric light source instead of a mirror.
- The
arm is also sometimes called the "body tube support."
- The
diaphragm is crucial for controlling light intensity and contrast.
This worksheet helps students learn the essential components of a compound light microscope and their functions.
