# Refracting Telescope Ray Diagram

Here we make a Keplerian telescope from simple elements and explain its operation using a ray diagram. This page supports the multimedia tutorial.

The refracting telescope works by bending light with lenses. the eyepiece lens and the objective lens are set to coincide (see diagram below).

Parallel rays of light from a distant object meet at the principal focus Fo of the objective lens. The refracting telescope works by bending light with lenses. the eyepiece lens and the objective lens are set to coincide (see diagram below).

Here we make a Keplerian telescope from simple elements and explain its operation using a ray diagram. This page supports the multimedia tutorial.A reflecting telescope is as shown below: In a reflecting telescope, an image is formed by reflection from a curved mirror. The image formed is then magnified by a secondary mirror.

Advantages of reflecting telescope over a refracting telescope are There is no chromatic aberration for reflecting telescopes as the objective is a mirror. 2. A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope).

The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used for long focus camera lenses. Jan 27,  · When you look up a ray diagram for a telescope you get the following: From reading my book it seems clear that the objective lens forms and image on the focal plane.

This then serves as an image for the eyepiece. Since the focal length of the eyepiece at the focal length of the objective lens you get a virtual image at infinity. Refracting 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 operation using a ray diagram. Refracting Telescopes The earliest telescopes, as well as many amateur telescopes today, use lenses to gather more light than the human eye could collect on its own. They focus the light and make distant objects appear brighter, clearer and magnified.

This type of telescope is called a refracting telescope.schoolphysics ::Welcome::Refracting Telescopes | Las Cumbres Observatory
