  1. The History of the Microscope

  2. What is a microscope?! • A biological tool which can be used to view objects that can’t be seen with the naked eye. • Objects such as… • Cells • Tissue • Microscopic Organisms Mosquito Blood Cells Amoeba

  3. 1000 AD • First visionary aid was invented. Known as a Reading Stone • What do we call these today?

  4. 1590 • Janssen and Janssen first experimented with multiple lenses in a tube • (First Compound Microscope) Compound Microscope Today

  5. 1665 (The Discovery of the “Cell”) • Robert Hooke viewed cork under his microscope. • Called them Cells

  6. 1674 (The Father of Microbiology) • Anton Van Leeuwenhoek • “Father of Microbiology” • Created Simple Microscope to view blood, yeast, and insects. • Invented knew methods in lens creation • Magnification up to 270 diameters

  7. 1700-1930’s • Improvements were made to increase magnification and viewing capabilities • 1830 - Jackson reduces the spherical abberations on lenses • Reduced Image Blur • 1903 – Zsigmondy develops ultramicroscope • Allowed scientists to view objects smaller than wavelength of light (Noble Prize 1925)

  8. 1931 (Electron Microscope) • Invented by Ernst Rusk • Uses electrons rather than light • Allows for the viewing of objects as small as the diameter of an atom. • Won Ernst Noble Prize in 1953 Rusk’s Electron Microscope (1930’s) Electron Microscope Today

  9. 1981 (Scanning Tunneling Microscope) • Invented by Binning and Rohrer • Allows for 3D magnification • Total Magnification 100,000,000X • Atomic Level • Birth of Nanoscience • Won Noble Prize 1986 Binning and Rohrer with their STM Silicon Atoms Surface of a piece of gold

  10. Today • In Class • Compound Light Microscope • Stereo Microscope • HRTEM (High Resolution Transmission Electron Microscope) • Worlds “Best” Microscope • For Scientific Use • Total Mag = 47,000,000X • AFM (Atomic Force Microscope) • Worlds Most Powerful Microscope • Allows scientists to view individual atoms • Total Mag = >100,000,000X
