Labeling the Parts of the Microscope | Microscope World Resources - Free Printable

The image shows a compound light microscope with labeled parts indicated by arrows. Below is the identification of each part based on standard microscope anatomy:

1. Eyepiece (Ocular Lens) – The lens at the top that you look through. It usually has a magnification of 10x.

2. Head (or Body Tube) – The part that connects the eyepiece to the objective lenses and holds them in place.

3. Arm – The curved part that supports the head and connects it to the base.

4. Objective Lenses – The set of lenses located beneath the stage, typically with different magnifications (e.g., 4x, 10x, 40x, 100x).

5. Stage – The flat platform where the slide is placed for viewing.

6. Stage Clips – The small metal clips that hold the slide in place on the stage.

7. Coarse Adjustment Knob – The larger knob used to move the stage up and down for initial focusing.

8. Fine Adjustment Knob – The smaller knob used for precise focusing after coarse adjustment.

9. Condenser – Located below the stage, it focuses light onto the specimen.

10. Diaphragm (Iris Diaphragm) – Controls the amount of light passing through the specimen; often located beneath the stage and above the condenser.

11. Base – The bottom part of the microscope that supports the entire structure and houses the light source.

12. Light Source (Illuminator) – Found at the bottom of the microscope, provides illumination for the specimen.

13. Nosepiece (Revolver) – The rotating part that holds the objective lenses.
