Microscopes Now and Then

  • Zaccaria Janssen and his son Hans

    They were experimenting with lenses in a tube. They found that things that are close look REALLY big. That was the fist compound microscope.
  • Robert Hooke

    He was the first person in history to ever use the word cell as the smallest unit in living things. HIs microscope had an oil lamp for lighting, and lenses to focus more on the thing being observed.
  • Leeuwenhoeken One-Lens Microscope

    His microscope only had one lens, but that one could magnify something up to 266 times, which is a lot looking at the old days. Microscopes now have the capability to make something 400 times larger than it is.
  • Ernst Abbe and Carl Zeiss Improved Microscope

    They already had the basics, so they decided to go up another step. They invented a microscope that was a compound light microscope. The image of the organism that we saw had better quality then the 1600 microscopes.
  • Ernst Ruska and his HUGE Level of Magnification

    He invented the first Transmission Electron Microscope. This microscope send electrons through the specimen, it has to be really thin though. It can magnify something up to 500,000 times. Now that thing must be REALLY detailed!
  • The Scanning Microscope

    This microscope sends electrons over something instead of through it. Instead of having a two dimensional picture, this microscope gives you a three dimensional view. It has a magnification of 150,000 times.
  • The Movement Detector Microscope

    This microscope is called a Scanning Tunneling Microscope. It measures the electrons that leak out of the specimen. This microscope is amazing. It has the magnification of 1,000,000 times.
