who invented the optical microscope ?

Answer 1

Anton Von Leeuwenhoek, i think

Answer 2

The first useful microscope was developed in the Netherlands in the early 1600s.[citation needed] There is almost as much confusion about the inventor as about the dates. Three different eyeglass makers have been given credit for the invention: Hans Lippershey (who also developed the first real telescope); Hans Janssen; and his son, Zacharias.

The most common type of microscope—and the first to be invented—is the optical microscope. This is an optical instrument containing one or more lenses that produce an enlarged image of an object placed in the focal plane of the lens(es). There are, however, many other microscope designs.

Answer 3

Antony van Leeuwenhoek is known to have made over 500 "microscopes," of which fewer than ten have survived to the present day. In basic design, probably all of Leeuwenhoek's instruments -- certainly all the ones that are known -- were simply powerful magnifying glasses, not compound microscopes of the type used today.

Answer 5

Galeleo Galili invented the first powerful telescope, but it's no more powerful than modern ones. He discovered Jupiter and the four moons.
