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.
Anton van Leeuwenhoek's most powerful microscopes were single-lens microscopes that he designed and crafted himself. These microscopes were capable of magnifying objects up to 300 times, allowing him to make groundbreaking discoveries in the field of microbiology.
The microscope made by Antonie van Leeuwenhoek that could achieve a magnification of 300X is known as a single-lens, or simple, microscope. It consisted of a single high-quality lens that van Leeuwenhoek handcrafted to achieve those magnification levels, allowing him to make pioneering observations of microorganisms.
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.
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.
Anthony van Leeuwenhoek referred to his early microscope as a "simple microscope" or "single-lens microscope." Unlike compound microscopes that used multiple lenses, his design utilized a single, high-quality lens to achieve significant magnification. This innovation allowed him to make groundbreaking observations of microorganisms and cells, earning him recognition as the "father of microbiology."

Antonie van Leeuwenhoek was a Dutch naturalist who used a simple microscope to make significant discoveries in the field of microbiology. He is known for being one of the first to observe and describe single-celled organisms, or "animalcules," among other microscopic organisms. His work laid the foundation for the field of microbiology.

Antony Van Leeuwenhoek, a Dutch scientist, became the first man to make and use a real microscope. He made superior lenses, by grinding and polishing a small glass ball into a lens with a magnification of 270x.
Zacharias Jansen, a Dutch spectacle maker, is credited with inventing the compound microscope in the late 16th century, which significantly enhanced the ability to observe microscopic details. This invention laid the groundwork for Anton van Leeuwenhoek, who used improved versions of the microscope to explore the microscopic world. Leeuwenhoek's discoveries of single-celled organisms and bacteria were made possible by the advancements in lens crafting and the optical innovations that Jansen initiated, enabling detailed observation and documentation of microscopic life.
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.
Because he described the microbial organisms, for the first time, with the help of microscopic observations.
