- Invented 1600s
- Microscopes more powerful today, work mostly same
- Pass light through glass lenses to magnify
- Powerful models about 2000x magnification
- Often stain cells- see organelles clearly
- More magnification = better
- Resolution = amount of detail- smallest distance between 2 points
- Electron microscope more powerful
- Electron microscopes- no light or lenses- pass beam of electrons through sample
- ^Then detect how many electrons pass through sample to get image
- Can see structures of organelles (nucleus etc)- electron
- Magnification = image size / real size
- Millimetre standard form: 1x10-3
- Micrometre…
