Study Notes
Microscope Parts and Functions
- Ocular Lenses (eyepieces): Magnification power of 10x.
- Body Tube: Connects the eye piece to the nosepiece and channels light.
- Arm: Supports upper components; serves as a handle for carrying.
- Nosepiece: Revolving mechanism for holding multiple objective lenses.
Objective Lenses
- Scanning Objective Lens: Shortest lens used for initial scanning, magnification power of 4x.
- Low-power Objective Lens: Longer than scanning lens, provides detail with magnification of 10x.
- High-power Objective Lens: Longest lens for higher detail, magnification power of 40x.
- Oil Immersion Objective Lens: Contains a 95x lens, used with immersion oil for maximum magnification.
Focusing Mechanisms
- Course Adjustment Knob: Used for initial focus, only compatible with low power objectives.
- Fine Adjustment Knob: Refines focus to achieve clarity on the specimen.
Light and Stage Components
- Condenser: Positioned below the stage, it focuses light onto the specimen for better visibility.
- Diaphragm: Regulates light intensity to optimize viewing conditions.
- Light Source: Provides illumination through the object being observed.
Structural Components
- Base: The grounded portion of the microscope that stabilizes it on the table.
- Stage: The platform holding slides for observation.
- Stage Clips: Keep slides secured on the stage.
- Mechanical Stage: Facilitates precise slide positioning through adjustable mechanisms.
