Robert Hooke
Robert Hooke studies various object with his microscope and publishes his results in Micrographia. Among his work were a description of cork and its ability to float in water. -
Bacteria
anton van Leeuwenhoek used one lens and he looked at blood and plants and was the first to describe bacteria. -
Blurring
Joseph Jackson Lister reduces the problem with spherical aberration by showing that several weak lenses used together at certain distances gave good magnification without blurring the image. -
Mathematical Theory
Ernst Abbe formulates a mathematical theory about the wave length of light. he gets the maxuim resolution -
Ultra Microscope
Richard Zsigmondy develops the ultramicroscope and is able to study objects below the wavelength of light. -
Colour
Frits Zernike invents the phase-contrast microscope that allows the study of colourless and transparent biological material. -
Electron Microscope
Ernst Ruska develops the electron microscope. The ability to use electrons in microscopy greatly improves the resolution and greatly expands the borders of exploration. -
the Tunneling Microscope
Gerd Binnig and Heinrich Rohrer invent the scanning tunneling microscope that gives three-dimensional images of objects down to the atomic level.
