WitrynaIsaac Newton (1642-1727, F.R.S. 1672, P.R.S. 1703-1727) is generally I credited with the invention of the reflecting telescope, having conceived the idea in 1666* (1, 2, 3). In fact Gregory (4) and others (5) had by that time already considered telescopes employing curved mirrors, but late in 1668 Newton was the first to construct a working ... 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. Newton's first reflecting telescope was completed in 1668 and is the earliest known functional reflecting telescope. The Newtonian telescope's sim…
WitrynaIn 1667 Isaac Newton devised a new kind of telescope that depends upon the reflective properties of a curved surface. A diagram of the Newtonian reflecting telescope (or reflector) is shown in Fig. 15-25.Parallel light rays from a distant source are incident on the mirror at the base of the instrument.
