Study Notes
Compound Microscope Components and Functions
- Eyepiece (Ocular Lens): Magnifies the specimen, providing an additional 10X magnification.
- Body Tube (Head): Connects the eyepiece to the objective lenses, allowing a direct line of sight.
- Arm: Serves as the structural support connecting the body tube to the base of the microscope.
- Stage: A flat platform where slides are placed for examination under magnification.
- Stage Clips: Metal clips that secure the slide firmly in place during observation.
- Base: Provides stability to the microscope and houses the illuminator for light source.
- Aperture: Hole in the stage permits light to reach the specimen for enhanced visibility.
- Power Switch: Controls the on/off functionality of the illuminator located at the base.
- Coarse Adjustment Knob: Adjusts the stage height quickly to bring the specimen into view.
- Fine Adjustment Knob: Offers precise focusing to sharpen the image of the specimen.
- Nosepiece: Revolving part that holds multiple objective lenses for different magnifications.
- Illuminator/Light Source: Projects light necessary for illuminating the specimen.
- Condenser: Focuses light onto the specimen to enhance clarity.
- Diaphragm: Regulates light intensity passing through the specimen for optimal detail.
- Diopter Adjustment: Corrects focus for individual eye differences, accommodating various users.
- Stage Height Adjustment (Stage Control): Allows movement of the stage in all directions for accurate focusing.
- Mechanical Parts: Supports and adjusts various components for smooth function.
- Magnifying Parts: Components that enlarge the appearance of the specimen.
- Illuminating Parts: Provide lighting to adequately illuminate the specimen for observation.
- Pillar: Vertical component that supports the microscope frame and vital parts.
- Inclination Joint: Allows tilting of the microscope for better viewing angles during use.
- Draw Tube: Houses the ocular lens for viewing through the eyepiece.
- Dust Shield: Protects objectives from dust accumulation, preserving image quality.
- Staining: Enhances visualization of specimens by adding color contrast.
- Mirror: Directs and focuses light for illumination, featuring concave and plane surfaces.
- Electric Lamp: Built-in light source suitable for use when natural light is insufficient.
- Magnification of Low Power Objective: Typically 10X magnification.
- Magnification of High Power Objective: Generally 40X or 43X magnification.
- Magnification of Oil Immersion Objective: Achieves higher magnification of 97X or 100X for detailed observation.
