The Newtonian telescope, also called the Newtonian reflector or just a Newtonian, is a type of reflecting telescope invented by the English scientist Sir Isaac Newton, using a concave primary mirror and a flat diagonal secondary mirror.

In the mid 1600s, Isaac Newton was studying light and found that the bands of color plaguing early astronomers were formed from light passing through a lens or a prism. He came to the conclusion that white light is really a mixture of light of different colors.

The first reflecting telescope built by Sir Isaac Newton in 1668 [3] is a landmark in the history of telescopes, being the first known successful reflecting telescope. [ 4 ] [ 5 ] It was the prototype for a design that later came to be called the Newtonian telescope .

2022年4月11日 · Sir Isaac Newton invented the reflecting telescope in 1668, a significant contribution to the field of optics that impacted the development of telescopes during the scientific revolution. His main innovation was the use of a concave mirror to gather light, which helped combat chromatic aberration and revolutionized telescope technology.

2018年3月23日 · It is commonly thought that Newton invented the first reflector telescope but it isn’t true. Credit for making the first reflector goes to an Italian Monk, Physicist, and Astronomer named Niccolo Zucchi. He published a book on Optics in the 1650s and it is this book that inspired Sir Isaac Newton to build his own telescope.

FIGURE 112: Newtonian reflector: simple telescope design invented and built by the famous English physicist, mathematician, and astronomer Sir Isaac Newton in 1672. First reflecting telescope was probably built by Niccolo Zucchi in 1616, but Newton was the first to introduce the diagonal flat - a simple solution his predecessors failed to see.

astronomers begin with is known as a Newtonian Reflecting Telescope, named after Sir Isaac Newton (1643-1727), the originator of this particular design. The type of mount that is most popular with amateurs is the Dobsonian Alt-Azimuth Telescope Mount, named for amateur telescope maker John Dobson (1915-2014), due to its portability and low cost.

2023年9月20日 · A Newtonian telescope, a type of reflecting telescope, was ingeniously invented by the renowned scientist Sir Isaac Newton. Newtonian telescope operates by employing a concave primary mirror and a flat secondary mirror to …

A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century by Isaac Newton as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic ...

SAAC Newton (1642-1727, F.R.S. 1672, P.R.S. 1703-1727) is generally credited with the invention of the reflecting telescope, having conceived the idea in I666* (I, 2, 3). In fact Gregory (4) and others (5) had by that time already considered telescopes employing curved mirrors, but late in I668 Newton was the first to construct a working model ...
