Study Notes
Compound Light Microscope Overview
- A compound light microscope uses light to illuminate specimens and two lenses to magnify images.
Components of the Microscope
-
Body Tube: Serves as a passageway for light, ensuring the correct distance between the lenses.
-
Eyepiece: Contains the ocular lens and is where the viewer looks to observe the specimen.
-
Stage: The platform upon which specimens are placed for examination.
-
Stage Clips: Secure the slide in position on the stage.
-
Nosepiece: Holds and allows for the rotation of objective lenses for more versatile viewing.
Objective Lenses
-
Low Power Objective: Shortest objective lens providing initial magnification.
-
High Power Objective: Longest objective with the highest magnification capabilities.
Focusing Mechanisms
-
Coarse Adjustment: Used for the initial focusing of the microscope, suitable only with low power objectives.
-
Fine Adjustment: Enables detailed focusing, intended for use with high power objectives.
Light Management
- Diaphragm: Located between the stage and light source, it regulates light intensity passing through the specimen.
Structure
-
Arm: Connects the stage to the eyepiece, providing structural support.
-
Base: The bottom part of the microscope, ensuring stability during use.
Imaging and Viewing
-
Magnification: Defined as the increase in apparent size of an object, calculated as ocular lens power multiplied by objective lens power.
-
Field of View: The observable area of the specimen through the eyepiece; important for assessing specimen details.
Specimen Representation
- Image in the Microscope: The specimen being viewed and analyzed under the microscope.
