Microscope Parts and Uses Quiz

Microscope Parts and Uses

• A microscope is an instrument that uses visible light and magnifying lenses to examine small objects. The word "microscope" combines "micro" (meaning small) and "scope" (meaning view).
• The common light microscope used in labs is a compound microscope, containing multiple lenses to magnify objects.
• The eyepiece is the lens closest to the eye.
• The objective lens is the lens closest to the specimen.
• Total magnification is calculated as the magnification of the eyepiece multiplied by the magnification of the objective lens.

Microscope Parts

• Eyepiece (Ocular): Used for viewing the magnified image.

• Body Tube: Connects the eyepiece to the objective lenses.

• Nosepiece: Rotates to change the objective lens.

• Objective Lenses: Different magnifications (e.g., 4x, 10x, 40x, 100x).

• Stage: Holds the specimen slide.

• Stage Clips: Hold the slide in place on the stage.

• Diaphragm: Regulates the amount of light passing through the specimen.

• Condenser: Collects and concentrates light onto the specimen.

• Coarse Adjustment Knob: Moves the stage up and down for initial focusing (large knob).

• Fine Adjustment Knob: Makes fine adjustments for precise focusing (smaller knob).

• Arm: Supports the microscope body.

• Base: Supports the entire microscope.

• Light Source (Bulb): Provides light for viewing.

• Illuminator: Provides light for viewing the specimen

• Trinocular Port : A port used for adding camera or other devices.

• Lamp: Provides light for viewing.

Microscope Types

• Brightfield microscope: A common type where the specimen is illuminated directly.
• Darkfield microscope: A type where the specimen appears light against a dark background.
