The Refracting Telescope: The Earliest Form Of Optical Telescope
The refracting telescope is a dipodic telescope, which means it uses various lenses to collect light in order to produce an image. The technology used in these telescopes was first used to form spy glasses and early telescopes, including the Galileo telescope. Today, refracting telescopes use the same technology that binoculars and long telephoto lens cameras use.
The First Use Of Refraction Technology
Refracting telescopes were first used around the early sixteen hundreds in the Netherlands. Around that time, Galileo, the great early astronomer, heard about this type of telescope and used what he knew about refraction technology to build his own version of the refracting telescope. Galileo was first thought to have invented the telescope that uses refracting technology, until it came out that it was first invented in the Netherlands.
The Use Of Lenses
The refracting telescope uses a convex objective to refract the light where it is then delivered to the eyepiece, another lens that allows the viewer to see the objects being amplified by the telescope. By using the refracting telescope, a viewer can see objects that are larger, brighter and clearer than he or she could with the naked eye. That makes refracting telescopes great for viewing the cosmos or for looking at objects far away, such as in the use of binoculars.
