Study Notes

Compound Microscope Components

Eyepiece/Ocular Lens: Contains the ocular lens; where the user looks to view the specimen.
Body Tube: Hollow cylinder that connects the eyepiece to the objective lenses, facilitating light passage.
Arm: Supports the structure of the microscope, connecting the base and the head.
Stage: Flat platform that holds slides or specimens in place for observation.

Focusing Mechanisms

Coarse Adjustment Knob: Used to make large adjustments to focus, suitable for low power objective lenses.
Fine Adjustment Knob: Used for precise focusing, particularly with high power objective lenses to enhance detail in the image.

Optical Elements

Revolving Nose Piece: Rotates to switch between different objective lenses, allowing varied levels of magnification.
Low-Power Objective Lens: Shorter lens offering lower magnification power, facilitating initial specimen location.
High-Power Objective Lens: Larger lens providing higher magnification for detailed observation of specimens.

Other Key Features

Stage Clips: Hold and secure slides on the stage, preventing movement during observation.
Light Source: Illuminates the specimen from below, enhancing visibility through the eyepiece.
Diaphragm: Located under the stage; adjusts the amount of light that reaches the specimen for optimal viewing.
Base: Provides stability and support for the entire microscope system.

Additional Microscopy Terminology

Objectives: Lenses mounted on the revolving nose piece that determine the magnification and resolution of the specimen viewed.
