Ray diagram of refracting telescope
WebReflecting telescopes use mirrors while refracting telescopes use lenses. A common model for a reflecting telescope is a Cassegrain telescope, which uses two mirrors. One collects electromagnetic radiation, and the other redirects it. The ratio of their focal distances determines the magnification power of the reflecting telescope. WebRefracting telescopes, including Keplerian telescopes or Galilean telescopes, use lenses to produce inverted, magnified, virtual images. Here we make a Keplerian telescope from simple elements and explain its …
