What did Robert Hooke discover through microscope?
While observing cork through his microscope, Hooke saw tiny boxlike cavities, which he illustrated and described as cells. He had discovered plant cells! Hooke’s discovery led to the understanding of cells as the smallest units of life—the foundation of cell theory.
What kind of microscope did Robert Hooke use?
compound microscope
Robert Hooke’s Microscope. Robert Hook refined the design of the compound microscope around 1665 and published a book titled Micrographia which illustrated his findings using the instrument.
How did Robert Hooke light his microscope?
To combat dark specimen images, Hooke designed an ingenious method of concentrating light on his specimens, as shown in the illustration. He passed light generated from an oil lamp through a water-filled glass flask to diffuse the light and provide a more even and intense illumination for the samples.
How many lenses did Robert Hooke used in his microscope?
Hooke’s microscope was a much larger, ‘compound’ instrument. It used three lenses: a small double-convex eye-lens at the top, then a large plano-convex field-lens, and another double-convex lens with a short focal length at the bottom of the tube.

Who invented the light microscope?
Light microscopes date at least to 1595, when Zacharias Jansen (1580–1638) of Holland invented a compound light microscope, one that used two lenses, with the second lens further magnifying the image produced by the first.
How old is the microscope?
In the late 16th century several Dutch lens makers designed devices that magnified objects, but in 1609 Galileo Galilei perfected the first device known as a microscope.
When was the first microscope made?
1590
1590: Two Dutch spectacle-makers and father-and-son team, Hans and Zacharias Janssen, create the first microscope.
Did Hooke invent the microscope?
Hooke devised the compound microscope and illumination system shown above, one of the best such microscopes of his time, and used it in his demonstrations at the Royal Society’s meetings.
Who made first microscope?
Zacharias Janssen
Every major field of science has benefited from the use of some form of microscope, an invention that dates back to the late 16th century and a modest Dutch eyeglass maker named Zacharias Janssen.
Who made microscope?
The development of the microscope allowed scientists to make new insights into the body and disease. It’s not clear who invented the first microscope, but the Dutch spectacle maker Zacharias Janssen (b. 1585) is credited with making one of the earliest compound microscopes (ones that used two lenses) around 1600.
