    Compound microscopes first appeared in Europe around 1620 [9] [10] including one demonstrated by Cornelis Drebbel in London (around 1621) and one exhibited in Rome in 1624. [ 11 ] [ 10 ] The actual inventor of the compound microscope is unknown although many claims have been made over the years.

    Whilst compound microscopes were first developed in the 1590s, the significance of the microscopic scale was only truly established in the 1600s when Marcello Malphigi and Antonie van Leeuwenhoek microscopically observed frog lungs and microorganisms. As microbiology was established, the significance of making scientific observations at a ...

[110] Microscopes were first developed with just two lenses: an objective lens and an eyepiece. The objective lens is essentially a magnifying glass and was designed with a very small focal ...

    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 ...
