| Two such glasses inclosed in a tube completed the invention of the simplest kind of the refracting telescope. |
| Newton was led by this reasoning to the erroneous conclusion that telescopes using refracting lenses would always suffer chromatic aberration. |
| Not only is the roof above them made of glass, it is also filled with water, further refracting the light received in the public spaces below. |
| Because glass does not transmit infrared radiation very efficiently, refracting telescopes are unsuitable for most kinds of infrared astronomy. |
| Knowing refracting corner of a prism, it could then calculate hades and refractions. |
| Examples of refracting afocal systems include an ordinary Keplerian telescope, a Galilean telescope, and a lens-erecting telescope. |
