What are the three main parts of the microscope describe each?
The three basic, structural components of a compound microscope are the head, base and arm.
- Head/Body houses the optical parts in the upper part of the microscope.
- Base of the microscope supports the microscope and houses the illuminator.
- Arm connects to the base and supports the microscope head.
What did Robert Hooke examine with 3 lens microscope?
Tiny Holes We Now Know As “Cells” It used three lenses and light. It lit up and enlarged whatever you put under it. Hooke placed a piece of cork under the new microscope. It allowed him to see something amazing.
What did Hooke discover about microscopes?
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 is a Hooke microscope?
This beautiful microscope was made for the famous British scientist Robert Hooke in the late 1600s, and was one of the most elegant microscopes built during the period. Hooke used a bi-convex objective lens placed in the snout and two additional lenses, an eyepiece lens and a tube or field lens. …
What are the 3 parts of the cell theory?
These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are mostly the same, both structurally and chemically; and finally, that energy flow occurs within …
What is Hooke known for?
English physicist Robert Hooke is known for his discovery of the law of elasticity (Hooke’s law), for his first use of the word cell in the sense of a basic unit of organisms (describing the microscopic cavities in cork), and for his studies of microscopic fossils, which made him an early proponent of a theory of …
How did Hooke improve the microscope?
Micrographia and Microscopy. In 1665, at age 30, Hooke published the first ever scientific bestseller: Micrographia. He further improved the microscope with lighting. He placed a water-lens beside the microscope to focus light from an oil-lamp on his specimens to illuminate them brightly.

Classification by structure
| Upright microscope | Observes targets from above. This type of microscope is used to observe specimens on slides. |
|---|---|
| Inverted microscope | Observes targets from below. This microscope is used to observe, for example, cells soaked with culture in a dish. |
Did Robert Hooke make his own microscope?
Hooke’s Microscope. This beautiful microscope was made for the famous British scientist Robert Hooke in the late 1600s, and was one of the most elegant microscopes built during the period. Hooke illustrated the microscope in his Micrographia, one of the first detailed treatises on microscopy and imaging. Although Hooke did not make his own…
What are the characteristics of a Hooke microscope?
The Hooke microscope shared several common features with telescopes of the period: an eyecup to maintain the correct distance between the eye and eyepiece, separate draw tubes for focusing, and a ball and socket joint for inclining the body.
When was the first microscope made?
These two- and three-lens microscopes were designed and used by Robert Hooke and made by Christopher Cock, London, shortly before 1665. It was the one he used for the observations in his landmark best-seller Micrographia.
How did Hooke light his specimens?
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.
