Microscope Timeline
How the microscope changed over time. -
The First Microscope
Zacharias Janssen make the first microscope by puting two lenses into a tube. -
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
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
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 can magnify things over 400x what we can see. And scanning electron microscopes can magnify objects up to 100 000x or more.
