Ernst Ruska & Max Knoll
The next great microscope invention, was the electron microscope. Co-Founders Ernst Ruska and Max Knoll (German) won half of the nobel prize in physics in 1986 for this invention. In this type of microscope, a vacuum speeds up all the electrons forcing their wavelength to be very short. This means that only one hundredth - thousandth of a wavelength speeds the electrons making them move very fast. In addition to this process, beams of white light caused by the short wavelengths, focus on a cell sample or any other slide, and are absorbed by the cells parts. On an electron sensitive photographic plate, this forms an image. This was a big part of microscope history, and currently, it is 66-3000 times more powerful than the light microscope.
