Microscope Parts and Functions
- Eyepiece: Contains a lens that magnifies images by 10X, allowing visual observation.
- Body Tube: Connects the eyepiece with objective lenses, ensuring proper alignment for light direction.
- Arm: Serves as a support structure connecting the body tube to the base; important for transportation.
- Revolving Nosepiece: Holds multiple objective lenses and allows for easy rotation to switch views.
- Objective Lenses: Further magnify specimens, available in various strengths: 4X, 10X, and 40X.
- Stage: The flat platform where slides with specimens are placed for examination.
- Stage Clips: Secure slides in place, preventing movement during observation.
- Condenser: Located under the stage, focuses light from the lamp through the stage hole onto the specimen.
- Diaphragm: Contains a rotating dial that regulates the light intensity coming through the condenser.
- Coarse Adjustment Knob: Adjusts the stage position in large increments for initial focusing; not for high power use.
- Fine Adjustment: Fine-tunes the stage movement for detailed focus; essential for high power observation.
- Base: The bottom support of the microscope that houses electronics and light source; aids in carrying.
- Lamp: Illuminates the specimen by sending light upwards through the condenser and the stage hole.
- Electron Microscope: Utilizes a beam of electrons instead of light, enabling high-resolution images of specimens.
