Electron microscopes are better than their optical counterpart. Electron microscopes use electrons to magnify a projected image, while optical microscopes use photons. Electron microscopes can reach magnifications of up to one million times.
This amplification is a lot compared to the limited magnifying power of optical microscopes of only one thousand times maximum magnifying power. Electron microscopes are said to launch a more thorough field than the hazy details of the optical microscopes, which are more expensive and challenging to maintain because they need to be fueled by a stable electrical source.
Electron microscopes generate grayscale images, while the optical microscope, on the other hand, is also known as the light microscope, and they are pioneering microscopes. They were the first designed mechanisms that made use of readily available simple lenses compared to the newer electron microscope.
