Simple telescopes of this general design are used for viewing astronomical objects. For viewing Earth objects, an additional lens or a prism must be used to produce an erect image. Telescopes that make use of the refractive property of lenses are called refracting telescopes or refractors.
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.
Refractor telescopes are usually expensive as compared to the results they deliver. Such type of telescope makes use of the phenomenon of refraction. Light strictly travels in a straight direction, away from (eg. Sun) source, in the form of microscopic particles. When they fall on a (transparent) object or mediums like water or glass.

Why was the reflecting telescope important? It was invented during the 1680s by Isaac Newton. These telescopes improved the before used refracting telescopes by giving a clearer picture.Reflecting telescopes also allow larger objects to be seen and are therefore ideal for …
Refractors, or refracting telescopes, are telescopes that use lenses as objectives to generate images. The objective lens refracts the incoming light to an eyepiece so the image can be seen. Larger aperture refracting telescopes are much more expensive, exponentially more expensive, than similar-sized reflectors. Therefore refractors are typically slimmer than reflectors. As the light does ...
These telescopes have a design made only of lenses, resulting in a lighter and more transportable telescope. Refractor telescopes are great for observing the planets and the moon, offering amazing contrast and sharpness. The closed tube offers protection against humidity and dust and there is almost no maintenance or cleaning needed.

Refractor Telescopes & Apochromatic Refractor Telescopes. Refractors are the optical design that most people associate with a telescope. Like any other telescope, their primary function is to gather as much light as possible, rendering distant objects brighter and easier to see when magnified.
Takahashi FC-100DZ Fluorite Refractor Telescope. The FC-100DZ is a fluorite doublet with a 100 mm aperture and an 800 mm focal length. In this doublet design, Takahashi has paired the fluorite element with a low dispersion glass having a high refractive index.

The history of the reflecting telescope goes back to 1668 when the famous British physicist and mathematician Sir Isaac Newton invented it as a replacement for refracting telescope.It was later named as the Newtonian telescope, which was constructed from a concave primary mirror and a flat diagonal secondary mirror.

Path of the light in a refracting telescope. Refracting telescopes are very rugged and sturdy — it is hard for the optics to come out of the alignment.Because of a long tube, the eyepiece is at the lower end of the telescope, meaning that for comfortable viewing, a high tripod is required.. Compared to other types of telescopes, refracting telescope has a small aperture.
15X-150X Magnification: Our refractor telescope is equipped with two eyepieces (H20mm and H6mm) and a 3X Barlow lens. The 3x Barlow lens trebles the magnifying power of each eyepiece.

Johannes Kepler also improved upon the early refracting telescopes. Instead of a concave and a convex lens, he tried two convex lenses. (Concave lenses curve inward, like a bowl, while convex lenses curve out.) The largest refracting telescope ever built had a lens 40 inches wide.
