He made 2.1 million microscopes
He didn't create the first microscope, Zacharias Janssen did.
The simple microscope, defined as having one lens, was enhanced by Leeuwenhoek. Many of the compound (multiple lensed) microscopes were blurry, but Leeuwenhoek ground his own lenses.
This famous man was the first man to create the microscope. He worked grounding glasses and found that by looking through the glass the image became bigger, and when he put the two lenses together it made it even bigger! This is how the microscope was created, the invention was made in Holland.
Short Answer:Around 1670, more than half a century after the discovery of the compound microscope, van Leeuwenhoek discovered a way to make small lenses of very high magnification that went significantly beyond the capability of existing microscopes.The microscopes of van Leeuwenhoek were simple single lens microscopes of a type that had been around for hundreds of years. His discovery was in the making of the lens. He did create more than two dozen variations on the design of the single lens microscope.More:Anton van Leeuwenhoek, (October 24, 1632 - August 26, 1723) is known as "the Father of Microbiology". He was from Delft, Netherlands. He was not trained in science, but was originally a tradesman.He is considered to be the first microbiologist because of his scientific discoveries made possible by his improvement of the microscope. He was the first person to observe and describe single-celled organisms. He was a contemporary of Robert Hook and the two men share some credit for establishing that living things were made of cells.Beyond the initial discovery of the method for making small spherical lenses, van Leeuwenhoek built a number of microscopes and experimented with their design.

yes
The dates are in dispute. The year of the single-lens optical microscope is usually given as 1590 (remarkable, in that Zacharias Jannsen's birth year is sometime between 1580 and 1588), and the year of the telescope as 1608.

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.
The diaphragm of a microscope focuses the light into the eye piece to create optimum viewing of the specimen.

Yes..They produce many during a lifetime.
Compound microscopes can be found in most Biology and science classrooms. They are electrically operated and use light to enhance the image of a cell. They will have multiple lenses for viewing.Dissecting microscopes are also known as stereo microscopes. They have low magnification and are also light powered. These microscopes can view objects larger than what a compound microscope is able to handle, in three dimensions.Scanning Electron Microscopes use electrons instead of light to create an image. These microscopes produce three-dimensional images with high resolution and magnification. They also have a larger depth of focus.Transmission Electron Microscopes use electrons instead of light to create an image. The material prepared must be very thin. The beams of electrons that pass through it give the viewer high magnification and resolution. These give two-dimensional images.Electron microscopes are one of the most advanced microscopes used today. This microscope is powered by a beam of electrons with very short wavelengths. These electrons strike objects that come in its path and helps increase the resolution of the microscope. The electron microscope is one of the types of microscopes used to study cells like tiny viral cells as well as larger molecules.
