Study Notes
Introduction to Microscopy
- Microscopy is a fundamental tool in biological research, used to magnify images of microscopic specimens.
- Key factors in microscopy include magnification, resolution, and the type of image produced (2D or 3D).
- Magnification is the ratio of an object's image size to its real size.
- Resolution is the ability to distinguish fine details in a structure.
- Light microscopy uses visible light while electron microscopy uses electrons.
- Light microscopy allows for observing live specimens, while electron microscopy requires killing the specimen.
- Electron microscopes have higher magnification and resolution than light microscopes.
Microscopy Branches
- Two main branches are light microscopy and electron microscopy.
- Light microscopy has advantages/disadvantages.
- Electron microscopy has advantages/disadvantages.
Compound Light Microscope Components
- The compound light microscope uses a series of lenses to magnify images.
- Mechanical components each have a function in image production.
- Components include an arm, base, light source, light intensity knobs, oculars, revolving nosepiece, and objective lenses.
- Specific microscope components have specific functions in microscopy
