How They Work. I am in the market for the larger, 90 mm version and need to sell this first. In other words, it uses two lenses to focus the light and make an object look much closer than it actually is. The tube holds the lenses in place at the correct distance from one another. Hans Lippershey of Middleburg, Holland, gets credit for inventing the refractor in 1608, and the military used the instrument first.Galileo was the first to use it in astronomy. Comprised of 21 chapters, this book begins with an introduction to physical ideas, with particular reference to the basic concepts used in describing and measuring things such as length, time, and mass.

Refracting telescopes are sometimes called 'dioptric telescopes'. Wide Field Of View. Unlike their catoptrics counterparts, refractors they use lenses as objectives in order to form visible images. We can represent this using a ray diagram which shows the path of imaginary rays of light passing through the telescope. Basically the objective lens produces an image of a distant object at its focus and the eyepiece lens magnifies this image. The Refractor telescope is the first type of telescope invented.
