Microscope

The first microscope to be developed was the optical microscope, although the original inventor is not easy to identify. Evidence points to the first compound microscope appearing in the Netherlands in the late 1590s, probably an invention of eyeglass makers there:[3] Hans Lippershey (who developed an early telescope) and Zacharias Janssen (also claimed as the inventor of the telescope). There are other claims that the microscope and the telescope were invented by Roger Bacon in the 1200s,[4] but this is not substantiated. Giovanni Fabercoined the name microscope for Galileo Galilei's compound microscope in 1625 [5] (Galileo had called it the "occhiolino" or "little eye").


There are many types of microscopes. The most common (and the first to be invented) is the optical microscope, which uses light to image the sample. Other major types of microscopes are the electron microscope (both the transmission electron microscope and the scanning electron microscope), the ultramicroscope, and the various types of scanning probe microscope.
On October 8, 2014, the Nobel Prize in Chemistry was awarded to Eric BetzigWilliam Moerner and Stefan Hell for "the development of super-resolved fluorescence microscopy," which brings "optical microscopy into the nanodimension".[1][2]
