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.
