Microscope Parts and Functions
- Base: Provides support to the microscope, ensuring stability during use.
- Arm: Integral for carrying the microscope securely; always hold the arm when transporting.
- Stage: Serves as a platform for placing slides containing specimens for examination.
- Stage Clips: Securely hold slides in place on the stage to prevent movement during observation.
- Eyepiece (Ocular Lens): Magnifies the specimen's image for the observer's view.
- Revolving Nosepiece: Houses multiple objective lenses and allows for easy rotation to switch lenses.
- Objective Lenses: Come in low-, medium-, and high-power options; provide varying magnification intensities.
- Coarse Adjustment Knob: A larger knob used primarily for general focusing under low power to achieve a clear image.
- Fine Adjustment Knob: A smaller knob for precise focusing, especially beneficial when using medium- or high-power objectives.
- Diaphragm: Regulates the amount of light that passes through the specimen, enhancing visibility.
- Light Source: Illuminates the specimen for optimal visibility and clarity during observation.
- Body Tube: Connects the eyepiece to the objective lenses, aligning the path of light.
- Proper Use: Always position the microscope on a flat, sturdy surface with the arm facing towards the user.
- Initial Focus: Begin focusing with the coarse adjustment knob while using the low-power objective lens for a general view.
- Adjustment Technique: After rough focusing, switch to the fine adjustment knob for sharper clarity with medium or high power.
- Slide Preparation: Position the slide on the stage ensuring the specimen is visible through the eyepiece and secure it with stage clips.
- Light Adjustment: Modify the diaphragm settings for adequate light control based on the specimen and objective lens in use.
