Refractors are the earliest type of optical telescope. The first practical refracting telescope appeared in the Netherlands about 1608, and were credited to three individuals, Hans Lippershey and Zacharias Janssen, spectacle-makers, and Jacob Metius. Galileo Galilei in about the month of May 1609, heard of the invention and constructed a version of his own. Refractors capture light with a lens that focuses it at the back of the tube. They are well-known for sharp viewing. They are also the most expensive telescope per inch of aperture .
