Study Notes
Microscope Review
- Microscope: A tool used to magnify objects, commonly used in biology
- Robert Hooke: Observed cork using a microscope, noting tiny boxes (cells)
- Anton van Leeuwenhoek: Known as the "father of microscopy," built over 240 microscopes, observed tiny organisms
-
Types of Microscopes:
- Compound Light Microscope
- Stereo Microscope
- Electron Microscope
- Magnification: A measure of how much an image is enlarged.
- Resolution: A measure of the clarity of an image
- Compound Light Microscope Function: Allows light to pass through a thin specimen using two lenses to create an image.
- Compound Light Microscope Magnification: 40x-400x
- Ocular Lens Magnification: 10x
- Objective Lens Magnification: Low (4x), Medium (10x), High (40x)
- Calculating Total Magnification: Multiply the ocular lens magnification by the objective lens magnification.
- Revolving Nosepiece: Allows changing the objective lenses.
- Stage: Holds the slide for viewing
- Diaphragm: Controls the amount of light entering the microscope
- Coarse Focus Knob: Moves the stage up and down, used for low power
- Fine Focus Knob: Moves the stage slightly for precise focus (used at all powers).
- Stage Clips: Hold the slides in place
- Stereo Microscope/Dissecting Microscope: Magnifies objects without needing thin samples, useful for studying surfaces.
- Electron Microscope Function: Uses electrons instead of light to view extremely small objects, achieves much higher magnifications than light microscopes.
- Electron Microscope Magnifications: 2000-10,000,000x
- Electron Microscope Usage: Large, expensive, generally used in hospitals, universities, etc.
- Compound Light Microscope Usage: Standard, most widely used.
