Study Notes
Microscope Anatomy
- Eyepiece/Ocular: The lens you look through to observe the specimen.
- Body Tube: Transmits light from the objective lens to the eyepiece, separating the nosepiece from the eyepiece.
- Nosepiece: Holds and allows rotation of objective lenses for changing magnification.
Focusing Mechanisms
- Coarse Adjustment Knob: Large knob used to initially focus the microscope by moving the stage vertically.
- Fine Adjustment Knob: Used for precision focusing after the specimen is initially focused, adjusting the stage slightly.
Stage Components
- Stage Clips: Hold the glass slide securely in place on the stage.
- Aperture: An opening in the stage allowing light to pass through to the slide.
- Diaphragm: Controls the amount of light passing through the aperture.
Specimen Support
- Slide: Thin glass piece that supports the specimen for observation.
- Stage: Flat surface where the slide is placed for viewing.
Lighting and Support
- Lamp or Mirror: Projects light through the aperture for clear visibility of the specimen.
- Microscope Legs: Support the instrument, housing the lamp or mirror.
Objective Lenses
- Objective Lens: Multiple lenses mounted on the nosepiece, each offering different levels of magnification.
- High Power Objective Lens: Typically 40x magnification, ideal for viewing fine details, yielding a total magnification of 400x with a 10x eyepiece.
- Low Power Objective Lens: Generally 10x magnification, useful for observing and analyzing slides.
- Scanning Objective Lens: The shortest lens, usually 4x, providing the lowest magnification, resulting in 40x total magnification with a 10x eyepiece.
- Oil Immersion Lens: 100x lens that provides the highest magnification (1000x with a 10x eyepiece), used with immersion oil.
Miscellaneous
- Base: The bottom support structure of the microscope.
- Power: Refers to the magnification level of a lens.
- Cover Slip: A glass or plastic piece placed over the specimen on a slide.
Calculating Magnification
- Total magnification is calculated by multiplying the power of the eyepiece by the power of the objective lens.
Specimen Observation Changes
- Increasing magnification results in seeing less of the specimen at once, but with enhanced detail.
Microscope Drawings
- Require accuracy and details, should include four important components: border, accurate depiction, title, and total power of magnification.
