No one exactly knows the exact number of how many electron microscopes there are in the world but the estimation would depend on how strong these microscopes are (as i dont know much about electron microscopes).
Simple Answer:History records that van Leeuwenhoek made about 500 lenses and used these in nearly 200 microscopes that he built which represented about 25 different microscope designs.Longer Answer:Anton van Leeuwenhoek's technical advancement was primarily that he invented a method for making small spherical lenses that much increased magnification of simple microscopes. (He did not invent the microscope.)Beyond the discovery of the methods for making small spherical lenses, van Leeuwenhoek also built microscopes and experimented with their design, addressing the difficult problems of illuminating, holding and viewing the specimens.He made over 500 optical lenses, though they did not go into 500 different microscopes. The microscopes themselves were expensive and time consuming to construct, but records indicate possibly as many as two hundred were made. In this process he is said to have created at least 25 variations on the basic design of the microscope.Only nine of his microscopes are known to exist today.
Light microscopes allow you to view living specimens and electron microscopes do not allow this.

yes archaeologists use microscopes
He made 2.1 million microscopes
In his lifetime Robertt Hooke made 4000 microscopes.
Yes..They produce many during a lifetime.
Leeuwenhoek was very good at improving microscopes through good lens grinding. He built as many as 500 microscopes in his lifetime. "He was able to study the structure of tissue, and was one of the first scientists to discover protozoa in water,"according to Bizarre Labs.com.

Anton van Leeuwenhoek invented the microscope in 1668. Throughout his lifetime, he made an estimate of five hundred microscopes. He also made various kinds of microscopes.

he didnt make a microscope he just updated it in the late 1690 (it might have been just before that)so he made 0 but he updated the origanal microscope
Microscopes use different amounts of lenses depending on the microscope.
