Study Notes
Microscope Parts and Functions
- Eyepiece: Lens located at the top of the microscope, with magnification powers typically at 10X or 15X.
- Tube: Connects the eyepiece to the objective lenses, forming the optical pathway for the image.
- Arm: Provides support for the tube and connects it to the base, enhancing stability during use.
- Base: The bottom structural component of the microscope that supports the entire apparatus.
- Illuminator: A consistent light source that replaces traditional mirrors for specimen illumination.
- Stage: A flat platform for placing slides, equipped with stage clips to secure them during observation.
- Revolving Nosepiece/Turret: Houses multiple objective lenses; facilitates easy rotation to switch magnification powers.
- Objective Lenses: Typically includes lenses of 4X, 10X, 40X, and 100X, producing total magnifications of up to 1000X when paired with a 10X eyepiece.
- Rack Stop: An adjustable feature that controls the minimum distance between the objective lens and the slide to prevent damage.
- Condenser Lens: Focuses light onto the specimen, improving illumination for better visibility.
- Diaphragm/Iris: Adjusts the intensity and size of the light beam directed upwards onto the slide, impacting image clarity.
- Coarse Adjustment Knob: A large knob for initial focusing; may move the stage or the upper part of the microscope for rapid adjustments.
- Fine Adjustment Knob: A smaller knob used for precise focusing after initial adjustments, ensuring sharp image clarity.
- Stage Clips: Keep slides securely in place on the stage to prevent movement during observations.
- Aperture: Opening in the stage that allows light to pass through for enhanced specimen viewing.
