Optical microscope. The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.
Microscopy. Scanning electron microscope image of pollen (false colors) Microscopic examination in a biochemical laboratory. Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye).

1936: Erwin Wilhelm Müller invents the field emission microscope. 1938: James Hillier builds another TEM. 1951: Erwin Wilhelm Müller invents the field ion microscope and is the first to see atoms. 1953: Frits Zernike, professor of theoretical physics, receives the Nobel Prize in Physics for his invention of the phase-contrast microscope.
Signature. Robert Hooke FRS (/ hʊk /; 18 July 1635 – 3 March 1703) [ 4 ][ a ] was an English polymath who was active as a physicist ("natural philosopher"), astronomer, geologist, meteorologist and architect. [ 5 ] He is credited as one of the first scientists to investigate living things at microscopic scale in 1665, [ 6 ] using a compound ...
Zacharias Janssen; also Zacharias Jansen or Sacharias Jansen; 1585 – pre-1632 [1]) was a Dutch spectacle-maker who lived most of his life in Middelburg.He is associated with the invention of the first optical telescope and/or the first truly compound microscope, but these claims (made 20 years after his death) may be fabrications put forward by his son.
Compound microscopes, which combine an objective lens with an eyepiece to view a real image achieving much higher magnification, first appeared in Europe around 1620. In 1665, Robert Hooke used a microscope about six inches long with two convex lenses inside and examined specimens under reflected light for the observations in his book ...
