(kat-ă-dÿ-op-trik)A telescope that uses both refraction and reflection to form the image at the prime focus. By introducing a full-aperturecorrecting platein front of the primary mirror, the telescope designer can correct manyaberrationsover an exceptionally wide field of view, in a way...
There are basically three types of optical systems in use in astronomical telescopes: refracting systems whose main optical elements are lenses which focus light by refraction; reflecting systems, whose main imaging elements are mirrors which focus light by reflection; and catadioptric systems, whose ...
There are 3 kinds ofastronomical telescopes: refraction type, reflection type and catadioptrictype: 1. refraction type is moreconvenient to use, larger vision, bright stars, but there is color difference,thereby reducing the resolution. The objective lens of high quality refractingmirror is two piec...

The principle of a telescope is based on ___. A. reflection of light B. refraction of light C. diffraction of light D. polarization of light 相关知识点: 试题来源: 解析 B。解析:望远镜的原理是基于光的折射。本题考查对望远镜原理的理解。反馈...
In both cases, parallel light coming from the distant object is entering through the entrance pupil, experiences refraction (reflection) at the lens (mirror), respectively, and is converging to form a real image in the focal plane. Sign in to download full-size image Figure 3. Refractor, ...
