Study Notes

Microscope Components

Body Tube: Separates the eyepiece lens from the objective lenses, essential for maintaining optical alignment.
Eyepiece: Contains the ocular lens which magnifies the image from the objective lenses, critical for viewing details of the specimen.
Coarse Focus Knob: Moves the stage over large distances to achieve a rough focus on the specimen quickly.
Fine Focus Knob: Allows for minute adjustments to the stage, providing precise fine-tuning for optimal clarity of the image.
Arm: Structural component that supports the body tube, providing stability to the microscope's framework.
Objective Lenses: Various lenses that focus and magnify light in different degrees; essential for providing various levels of magnification.
Stage Clips: Mechanically secure the slide in position on the stage, preventing movement during observation.
Nosepiece: Flicks the objective lenses into position, facilitating easy change between magnifications for versatile viewing.
Stage: Flat platform that supports the slide where the specimen is mounted for examination.
Lamp: Illuminates the specimen by projecting or reflecting light upward through the diaphragm, crucial for visibility.
Base: The foundational support of the microscope, ensuring stability and proper balance during usage.
Diaphragm: Adjusts the intensity of light passing through the stage opening, which is vital for achieving the desired contrast in the image.
