Refracting Telescope Ray Diagram
Refracting Telescopes If a lens is convex or converging, it takes parallel light rays from a distant object and bends them so Refraction telescope ray diagram .
Astronomical Refracting Telescope. ray diagram for an astronomical refracting telescope. The angle subtended by the object α (alpha), is given by: astronomical .
Ray Diagrams. Telescopes work by collecting a lot of light and then use mirrors ( Reflecting telescopes) or lenses (Refracting telescopes) to focus that light, i.e.
to . Here we make a Keplerian telescope from simple elements and explain its operation using a ray diagram.

Jul 08, · An explanation of how to draw a lens ray diagram for an astronomical telescope, including a quick derivation of the formula for angular magnification. A simple refracting telescope consists of two lenses, the Objective and the eyepiece.
Basically the objective lens produces an image of a distant object at its focus and the eyepiece lens magnifies this image. We can represent this using a ray diagram which shows the path of imaginary rays of light passing through the telescope.
Ray Diagrams.
The example ray diagram above shows three imaginary “rays” of light being reflected off a mirror and then going through a lens. You can see where the focus is by looking where the “rays” cross each other.
It is the lens that is making the light focus. This arrangement is useful when optical equipment is being used that is too heavy to mount directly on the telescope. Reflecting telescopes have many advantages over refracting telescopes.
Mirrors don’t cause chromatic aberration and they are easier and cheaper to build large. The are also easier to mount because the back of the mirror can be.Ray Diagrams | National Schools’ ObservatoryWhat is a Refracting Telescope?
