Comprehensive Analysis

1) "Telescope" -- As to telescope refractor 1tele·scope Pronunciation: 'te-l&-"skOp Function: noun Usage: often attributive Etymology: New Latin telescopium, from Greek tEleskopos farseeing, from tEle- tele- + skopos watcher; akin to Greek skopein to look -- more at SPY 1 : a usually tubular optical instrument for viewing distant objects by means of the refraction of light rays through a lens or the reflection of light rays by a concave mirror -- compare REFLECTOR, REFRACTOR 2 : any of various tubular magnifying optical instruments 3 : RADIO TELESCOPE Pronunciation Symbols For other senses of this word, see Telescope (disambiguation). A telescope (from the Greek tele = 'far' and skopein = 'to look or see'; teleskopos = 'far-seeing') is an instrument designed for the observation of remote objects. The term usually refers to optical telescopes, but there are telescopes for most of the spectrum of electromagnetic radiation and for other signal types. 1 Types of telescopes 1.1 Optical telescopes 1.2 Radio telescopes 1.3 X-ray and gamma-ray telescopes 1.4 High-energy particle telescopes 2 Other types 3 Some famous telescopes 4 See also 5 External links 50 cm refracting telescope at Nice Observatory. An optical telescope gathers and focuses light mainly from the visible part of the Electromagnetic spectrum (although some work in the infrared and ultraviolet). Optical telescopes increase the apparent angular size of distant objects, as well as their apparent brightness. Telescopes work by employing one or more curved optical elements - lenses or mirrors - to gather light or other electromagnetic radiation and bring that light or radiation to a focus, where the image can be observed, photographed or studied. Optical telescopes are used for astronomy and in many non-astronomical instruments including theodolites, transits, spotting scopes, monoculars, binoculars, camera lenses and spyglasses. There are three main types: The refracting telescope which uses solely an arrangement of lenses. The reflecting telescope which uses solely an arrangement of mirrors. The catadioptric telescope which uses a combination of mirrors and lenses. The 76.0m Lovell radio telescope at Jodrell Bank Observatory. ..." 2) "Refractor" -- As to telescope refractor re·frac·tor Pronunciation: ri-'frak-t&r Function: noun : a telescope whose principal focusing element is a lens Pronunciation Symbols Image of a refracting telescope from the Cincinnati Observatory in 1848 A refracting or refractor telescope is a dioptric telescope that uses a lens as its objective to form an image. The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used in other devices such as binoculars and long or telephoto camera lenses. 1 Invention 2 Refracting telescope designs 2.1 Galilean telescope 2.2 Keplerian Telescope 2.3 Achromatic refractors 2.4 Apochromatic refractors 3 Technical considerations 4 Notable refracting telescopes 5 See also Refractors were the earliest type of optical telescope. The first practical refracting telescopes appeared in the Netherlands about 1608, and were credited to three individuals, Hans Lippershey and Zacharias Janssen, spectacle-makers in Middelburg, and Jacob Metius of Alkmaar also known as Jacob Adriaanszoon. Galileo, happening to be in Venice in about the month of May 1609, heard of the invention and constructed a much improved version of his own based on his understanding of the effects of refraction. Galileo then communicated the details of his invention to the public, and presented the instrument itself to the doge Leonardo Donato, sitting in full council. Galileo may thus claim to have invented the refracting telescope independently, but not until he had heard that others had done so. A typical refractor has two basic elements, a convex objective lens and an eyepiece lens. The objective in a refracting telescope refracts or bends light at each end using lenses. This refraction causes parallel light rays to converge at a focal point; while those which were not parallel converge upon a focal plane. This can enable a user to view the image of a distant object as if it ..."
