- Both use radiation to form larger and more detailed images of objects
- Light Microscope
- Radiation: Light
- Used in study and research for biology and medical sciences
- Less Expensive
- Image formation using light via glass lenses
- Use the colours provided by visible light to see image
- Image can be viewed directly by the eye
- Electron Microscope
- Used in study and research for biology and medical sciences
- Uses beams of electrons rather than rays of visible light
- Radiation: Electron Beams
- Specimens must be carefully prepared in the correct way for both the equipment and the sample
- Light Microscope
- Radiation: Light
- Less Expensive
- Image formation using light via glass lenses
- Use the colours provided by visible light to see image
- Image can be viewed directly by the eye
- Light Microscope
- More expensive
- Use light with a wavelength of 400-700 nm
- Uses electron beams of approximately 1 nm wavelength
- Image formation using electromagnets to focus beams of electrons
- Higher magnifications
- Produce Grey-scale images or 'false-colour' micrograph images
- Requires use of fluorescent screen, photographic plate or electronic display to view the image because electrons cannot be seen by the human eye
- Living specimens cannot be viewed through an electron microscope because it requires it to be vacuum in the tube
- Light Microscope
