Because glass does not transmit infrared radiation very efficiently, refracting telescopes are unsuitable for most kinds of infrared astronomy. |
On a smooth surface, a fingerprint can stand out on its own, refracting light differently than the surface below. |
Examples of refracting afocal systems include an ordinary Keplerian telescope, a Galilean telescope, and a lens-erecting telescope. |
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. |
You can also combine our zoom and wide angle lenses using our adapter with astronomical refracting telescopes. |
It acted like a prism on the setting sunlight striking it, refracting the light in much the same way as a crystal would. |
