Short Answer:
Antonie (Anton) van Leeuwenhoek made innovations to the simple one lens microscope making it perform much better than existing compound microscopes.
His microscopes received no special name, just "simple microscope." Van Leeuwenhoek always referred to his instrument as a Vergroot-glas, which translates into magnifying glass.
His microscopes consisted of one small glass sphere, just over a millimeter wide, and the device to hold the lens and specimen made from brass, copper or silver, that was the size of a human hand. Both lens and holder were fabricated by entirely by van Leeuwenhoek.
His breakthrough occurred around 1670, when he invented a method for making smaller spherical lenses with much greater magnification; the best in the world at the time. He ultimately discovered single celled microorganisms and other microscopic structures of plants, animals and minerals.

Anton van Leeuwenhoek, (October 24, 1632 -- August 26, 1723) is given the title of "the Father of Microbiology" and sometimes "the Father of Microscopy" though biographers of Louis Pasteur or Zacharias Janssen sometimes award the same titles to them. Van Leeuwenhoek was from Delft, the Netherlands. He was not trained in science, but was a tradesman who regularly employed a microscope to view the weaving of fine cloth.
The date is not known precisely, but around 1670, van Leeuwenhoek discovered a way to make small spherical lenses of very high magnification that went significantly beyond the capability of existing compound microscopes that were limited to 30 times magnifying power. Eventually he would make lenses over 250 times magnifying power.
He is considered to be the first microbiologist because of his scientific discoveries made possible by his enhanced microscopes. He was the first person to observe and describe single celled organisms, including protozoans, sperm and bacteria. He was a contemporary of Robert Hooke and the two men share some credit for establishing that living things were made of cells.
After discovering the secret for making small spherical lenses, van Leeuwenhoek went on for 50 years making over 500 optical lenses and around 200 microscopes. The microscopes represent at least 25 variations on his basic design. Nine of these microscopes, as well as a few of his original specimens, exist in museums today.

What year did Anton Van Leeuwenhoek invent the microscope?
Anton van Leeuwenhoek did not invent the microscope. The compound microscope was invented 40 years before Anton van Leeuwenhoek was born. The simple microscope was known 300 years earlier. Anton van Leeuwenhoek invented a method for making small spherical lenses that much increased the magnification of simple microscopes. The date is not know precisely, but 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. He advanced the design of the simple microscope. He used his inventions to make great discoveries into the world of microorganisms.
How did zacharias janssen make Anton van leeuwenhoeks discoveries possible?
There is no apparent connection between van Leeuwenhoek who developed his simple (single lens) microscope system and the work of Zacharias Janssen is associated with the compound (two lens) microscope invented in 1590. Van Leeuwenhoek was unable to use the compound microscope because magnification was too low. The microscopes built by van Leeuwenhoek (around 1670) had ten times the magnification of the compound microscopes of the day. One could say that Janssen helped van Leeuwenhoek succeed by getting everyone else to use the inferior microscope.
What was van Leeuwenhoek's microscope called?
Simple Answer:Antonie (Anton) van Leeuwenhoek made innovations to the simple microscope with a single lens. His microscopes received no special name and were enhancements of the "simple microscope."Anton van Leeuwenhoek always referred to his instrument as a Vergroot-glas, which translates into magnifying glass.He also enhanced the overall design of the simple microscope and specimen holder. He constructed at least 25 different designs of the simple microscope. (He rarely used the compound microscope which had been invented 40 years before his birth because his simple microscopes had far greater magnification.)More:Though Anton van Leeuwenhoek did not invent the microscope, he did make a great discovery. About 1670, he found that he could form tiny glass beads that were nearly perfect spheres and also capable of high magnification when used in a simple microscope. Indeed, his little glass spheres could magnify an object 250 times (perhaps more), about ten times better than the best compound microscopes of the day.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 necessarily 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.
How was the first compound microscopes different from Leeuwenhoek?
Compound microscopes have more than one lens. The first (objective) lens magnifies the object to produce an image. Subsequent lenses magnify an image produced by a previous lens. Leeuwenhoek's "microscope" had only one lens -- simple magnification only. ~The Undertaker~

What did Anton van leeuwenhoek see in 1673?
Anton Van Leeuwenhoek saw a penis in the microscope, it had sperm hanging out of it and it was big and juicy, he went to suck it and it became a man so he was sucking a mans penis and he was full of joy. make you horny? haha im kidding im kidding, i have no idea what he saw.. it was like 400 years ago, who should care?
How did the Leeuwenhoek microscope work?
Anton van LeeuwenhoekAnton van Leeuwenhoek (1632 to 1723) was a Dutch cloth merchant who made literally hundreds of microscopes. Although compound lenses were invented at that time, they were not yet perfected, and so Leeuwenhoek's microscopes all worked based on a more simple magnification system. Leeuwenhoek's skill as a lens grinder was essential to the success of his microscopes and enabled him to make what were essentially glorified magnifying glasses that could magnify an object up to more than 100 times.The Basic Leeuwenhoek MicroscopeThe standard Leeuwenhoek Microscope is composed of four parts: a small lens to magnify the object, a spike to hold the object in front of the lens (and rotate it if need be), a screw to adjust the position of the object and a large base plate to hold it all together. The object is impaled upon the spike, and the screws are used to rotate the object and move it closer to or farther from the lens.How It WorksThe object is held firmly in place behind the lens, which creates a virtual image of the object that is larger than the actual object. By placing the object closer to the convex lens than the actual focal length of the lens, the object becomes closer than the intended focus, and thus appears larger in the image created in the lens.The skewered object, in the case of the Leeuwenhoek Microscope, is held firmly in place behind the lens closer than the focal point of that convex lens. However, since each individual has a different focal length, an adjustment screw is provided to vary the distance between object and lens to make sure that optimum magnification can be achieved.
Why did Anton make the microscope so small?
Because he is...
Who developed the light microscope?
It was developed, and then you might say improved or modified over time. Zaccharias Janssen and Hans Janssen experimented with lenses that would help make the light microscope, as did Galileo. Anton van Leeuwenhoek also experimented with microscopes and so did Robert Hooke.
