  • The Second Microscope

    The Second Microscope
    Anton van Leeuwenhoek used a simple microscope with only one lens to look at blood, insects and lots of other objects. He was first to describe cells and bacteria, seen through his very small microscopes. And for his time, very good lenses.
  • The Microscope Gets Technical

    The Microscope Gets Technical
    A couple technical changes make microscopes better and easier to use, which makes to microscopy become more popular among scientists. An important discovery is that lenses with two types of glass could reduce the chromatic effect, with its disturbing halos resulting from differences in refraction of light.
  • The Electron Microscope

    The Electron Microscope
    Ernst Ruska developed the electron microscope. The ability to use electrons in microscopy greatly improves the resolution. It allowed people to see the fine details inside and outside of cells, small creatures and many other things.
  • The Microscope Today

    The Microscope Today
    The microscope today can magnify things over 400x what we can see. And scanning electron microscopes can magnify objects up to 100 000x or more.
