Difference Between Electron Microscope and Light Microscope
Light Microscope
Uses light (approx 400-700 nm) as an illuminating source.
Lower magnification than an electron microscope.
No risk of radiation leakage.
Specimen preparation takes about a few minutes or an hour.
The image is seen through the ocular lens. No screen needed.
Useful magnification of 500x to 1500x.
Low resolution.
Inexpensive and requires a low maintenance cost.
Electron Microscope
Uses electron beams (approx 1 nm) as an illuminating source.
Higher magnification.
Risk of radiation leakage.
Specimen preparation takes several days.
Only dead and the dried specimen can be seen.
The image formation depends upon the electron scattering.
The image is received on a zinc sulfate fluorescent screen.
Direct magnification as high as 16000x and photographic magnification as high as 1000000 x.
High resolution.
Expensive and high maintenance.
