Study Notes
Microscopy
- Microscopes are devices with magnifying lenses, used to view detailed, enlarged images of small objects.
- Two main functions:
- Magnification: Enlarges the image, akin to zooming in on a specimen.
- Resolution: The level of detail visible, determining the ability to distinguish two points as separate. Resolution increases with magnification.
- Types of microscopes:
- Light microscopes
- Electron microscopes
- Dissecting microscopes
- Electron microscopes provide extremely high magnification, up to 1,000,000x, allowing observation of incredibly small details within cells (sometimes down to molecular level).
- Typical parts of a light microscope include:
- Eyepiece lens (ocular lens)
- Body tube
- Revolving nosepiece
- Objective lenses
- Stage
- Stage clips
- Diaphragm
- Light source
- Coarse adjustment knob
- Fine adjustment knob
- Arm
- Base
Using a Microscope
- Place slide on stage and secure with stage clips.
- Adjust nosepiece to the lowest power objective lens.
- Look through the eyepiece.
- Use coarse focus knob to bring the specimen into view.
- Use fine focus knob for precise focusing.
