First reflective telescope
WebInstead of using a lens to focus the light from a star, Newton used a mirror. He experimented with different metals and polishing methods and made his first reflecting telescope in 1668. Newton was not the only astronomer … WebA typical astronomical telescope of this time was the one made in 1656 by Christiaan Huygens, a Dutch mathematician and astronomer, and his brother Constantine. 23 feet long, it magnified objects about a hundred times, and still had a considerable field of view.
First reflective telescope
Did you know?
The Newtonian telescope was the first successful reflecting telescope, completed by Isaac Newton in 1668. It usually has a paraboloid primary mirror but at focal ratios of about f/10 or longer a spherical primary mirror can be sufficient for high visual resolution. See more 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 See more A curved primary mirror is the reflector telescope's basic optical element that creates an image at the focal plane.

Objects resembling lenses date back 4000 years although it is unknown if they were used for their optical properties or just as decoration. Greek accounts of the optical properties of water-filled spheres (5th century BC) were followed by many centuries of writings on optics, including Ptolemy (2nd century) in his Optics, who wrote about the properties of light including reflection, refraction, and color, …

If inventing means the first to design and build a minimally functional reflecting telescope then the inventor is Isaac Newton (1668). History is not always cut and dried.

WebThe first reflecting telescope was built in the 17th century. Ideas about the construction of such a telescope were circulating at that time. We have reports of experimental reflecting telescopes having been built before 1668, but without confirmation.
