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 … See more The idea that curved mirrors behave like lenses dates back at least to Alhazen's 11th century treatise on optics, works that had been widely disseminated in Latin translations in early modern Europe. Soon after the invention … See more Nearly all large research-grade astronomical telescopes are reflectors. There are several reasons for this: • Reflectors work in a wider spectrum of light since … See more Prime focus In a prime focus design no secondary optics are used, the image is accessed at the focal point of the primary mirror. At the focal point is some type of structure for holding a film plate or electronic detector. In the past, in very … See more • Who was James Gregory?

Both lenses are in a shape thats called 'convex'. Convex lenses work by bending light inwards. Reflecting telescopes, on the other hand, dont use lenses at all. Instead, they use mirrors to focus the light together. WebJul 15, 2024 · A catadioptric telescope's moving parts are more complex than those found in refractor or reflector telescope. 4. Catadioptric telescopes have an inherent optical performance limitation based on the central obscuration of their aperture caused by their own secondary mirror.
