Eyepiece (Ocular lens): Magnifies the image from the objective lens and allows the observer to view the specimen.

Here are the functions of each numbered part of the microscope: 1. Eyepiece (Ocular lens): Magnifies the image from the objective lens and allows the observer to view the specimen. 2. Eyepiece tube (Body tube): Holds the eyepiece and connects it to the objective lenses. 3. Revolving nosepiece: Rotates to switch between different objective lenses, changing the magnification. 4. Objective lenses: Primary lenses that magnify the specimen, located closest to the slide. 5. Stage clips: Hold the microscope slide firmly in place on the stage. 6. Stage: A flat platform where the specimen slide is placed for viewing. 7. Diaphragm (Iris diaphragm): Controls the amount of light passing through the specimen. 8. Condenser: Gathers and focuses light from the illuminator onto the specimen. 9. Light source (Illuminator/Mirror): Provides light to illuminate the specimen. 10. Base: The bottom support structure of the microscope, providing stability. 11. Fine adjustment knob: Used for small, precise adjustments to bring the specimen into sharp focus, especially at high magnifications. 12. Coarse adjustment knob: Used for large adjustments to move the stage up or down, bringing the specimen into approximate focus. 13. Arm: Connects the head of the microscope to the base and is used for carrying the instrument. 14. Base (foot): The broad, heavy bottom part of the microscope that provides stability. 15. Coarse adjustment knob: (Same as 12) Used for large adjustments to move the stage up or down, bringing the specimen into approximate focus. 16. Fine adjustment knob: (Same as 11) Used for small, precise adjustments to bring the specimen into sharp focus, especially at high magnifications. 17. Stage: (Same as 6) A flat platform where the specimen slide is placed for observation. 18. Stage clips: (Same as 5) Securely hold the microscope slide in place on the stage. 19. Arm: (Same as 13) Connects the head of the microscope to the base and is used for carrying the instrument. 20. Body tube: (Same as 2) Holds the eyepiece and connects it to the objective lenses, ensuring proper alignment. 21. Arm/Frame: (Same as 13 and 19) The main structural support connecting the optical components to the base, used for carrying.
