Did Galileo design refracting telescopes

Answer 1

Many historians explain that Galileo was the first person to use a telescope. In 1610 Galileo discovered Saturn's rings. He also observed Jupiter's four moons and viewed the different phases of Venus. This lead to the study of sunspots and various celestial activities. Even though Galileo is credited with being the first to make practical improvements and enhancements to the use of the telescope, he was not the inventor, and therefore not the first person to use a telescope. That person would be Hans Lippershey. Hans Lippershey was born 1570 in Germany, but was raised in Holland. He invented the first refracting telescope in 1608. A lens maker, he designed this telescope from two lenses and applied for a patent, intending that it would be important for the military. He successfully demonstrated the usefulness of his refracting telescope to the military.

Answer 2

No, Galileo's telescope used lenses (which refract light) to focus light and it was therefore a 'refractor'.

Reflector telescopes 'reflect' light using shaped mirrors to bring it t a focus.

Answer 3

Yes. Galileo's telescopes were refractors with a large object lens at the top end.

The type of refractor is now called a 'Galiean' telescope in which the eye lens is a concave lens. This type of telescope is now only used in cheap telescopes and binoculars with low magnification. Modern refractors have an eye lens with one or more usually two convex lenses that provide an inverted image. A further pair of lenses can give an image the right way up if desired, for naval use.

Answer 4

Galileo just used the refracting telescope.

Answer 5

The classical Galileo telescope was a refractor telescope, i.e. a telescope using lenses instead of mirrors.
