It was a tube with lenses at each end. The magnification ranged from 3X to 9X depending on the size. The eyepiece lens was bi-convex and the far end lens was plano-convex.
The compound microscope was invented by Zacharias Janssen in the late 16th century, although others like Hans and Zacharias Janssen, Hans Lippershey, and Hans Martens claim to have contributed to its development. The electron microscope was later invented in the 20th century by Ernst Ruska and Max Knoll.
Zacharias Janssen, credited with inventing the compound microscope in the late 16th century, likely first looked at small objects like threads or insects. However, the specific details of his initial observations are not well-documented. His invention laid the groundwork for future advancements in microscopy, allowing for the examination of microscopic life and structures.
Actulley lots of scientists made the microscope. At first the microscope started out as just being as useful as magnifying glass but soon got better over the years to be what it is now today. The microscope was invented to see microbes. What was in cells and mainly to see how diseases were spread, what caused diseases, and how to prevent them.
from the Wikipedia article on microscopes: Microscopes trace their history back almost 1200 years with Abbas Ibn Firnas's corrective lenses, and it was Ibn al-Haytham's Book of Optics, written between 1011 and 1021, that laid the foundation for optical research on the magnifying glass. Also, a device called the reading stone by an unknown inventor (thought to be Ibn Firnas) magnified text when laid on top of reading materials. The first true microscope was made around 1595 in Middelburg, Netherlands. Three different eyeglass makers have been given credit for the invention: Hans Lippershey (who also developed the first real telescope); Sacharias Jansen; and his son, Zacharias. Giovanni Faber is credited with coining the name "microscope" which he gave to Galileo Galilei's compound microscope in 1625. Anton Van Leeuwenhoek, the "Father of Microbiology", later developed a new, improved microscope which allowed people to see microscopic things in the biological realm, like bacteria and spermatozoa, which no human had ever seen before.
The microscope's diaphragm controls the amount of light entering the microscope, which helps to adjust the contrast and brightness of the specimen being viewed. By adjusting the diaphragm, you can improve the clarity and visibility of the image.

No, he did not invent anything other than the microscope. on the day that he had invented this extraordinary contraption it had changed the way we looked at thing so small (like cells) forever.
Robert Hooke is credited with inventing the compound microscope, which used a series of lenses to magnify images. He did not invent multiple microscopes, but his work in improving the design of the compound microscope contributed to advancements in the field of microscopy.

Zacharias Janssen's microscope, developed in the late 16th century, typically consisted of a simple tube with a couple of lenses at either end. It often resembled a long, narrow cylinder, with one lens serving as the eyepiece and another as the objective lens. The design was rudimentary compared to modern microscopes, lacking advanced features like adjustable focus or illumination. Despite its simplicity, it was crucial in the early development of optical instruments and microscopy.
The first microscope to be developed was the optical microscope. An early microscope was made in 1590 in Middelburg, Netherlands. Two eyeglass makers are variously given credit: Hans Lippershey (who developed an early telescope) and Zacharias Janssen. Van Leeuwenhoek improved a microscope and first described cells seen in cork tissue. He called them cells as they looked like little rooms, similar to ones that monks lived in.
Zacharias Jansen did not leave behind any famous quotes as he was a Dutch spectacle-maker credited with inventing the first compound microscope in the late 16th century. Jansen's invention revolutionized the field of microscopy and laid the foundation for advancements in scientific research and understanding of the microscopic world. While his contributions were significant, he is not known for any specific quotes.
The reason Zacharias Janssen called cells, cells is that when he looked at them they looked like actual cells like in jail or prision. hint cells

The development of the microscope spanned several centuries, with the first compound microscope being created around the late 16th century, attributed to Zacharias Janssen and Hans Lippershey. However, significant advancements were made over the following decades and into the 17th century, particularly by scientists like Antonie van Leeuwenhoek and Robert Hooke. Therefore, while the initial creation took a relatively short time, the evolution into more sophisticated models occurred over a long period.
Zacharias Janssen was a Dutch spectacle maker credited with inventing one of the first compound microscopes in the late 16th century. While he did not have a direct connection to the Bell Telephone Company, his invention of the microscope laid foundational work in optics, which eventually influenced developments in telecommunications technologies. The Bell Telephone Company, founded by Alexander Graham Bell in 1877, relied on advancements in electrical engineering and optics, reflecting the long-term impact of early optical innovations like Janssen's.
