The design Galileo Galilei used c. 1609 is commonly called a Galilean telescope. [5] It used a convergent (plano-convex) objective lens and a divergent (plano-concave) eyepiece lens (Galileo, 1610). [6] A Galilean telescope, because the design has no intermediary focus, results in a non-inverted (i.e., upright) image. [7]
By using two types of glass for the two lenses this gets compensated to some degree, resulting in a sharper and clearer image. Depending on the configuration, 4, 6 or 8 lenses are used. The 4-lens configuration results in a telescope in some ways similar to Galileo's, with 17× magnification and a very small field of view.
Notes on Hans Lippershey's unsuccessful telescope patent in 1608. The first record of a telescope comes from the Netherlands in 1608. It is in a patent filed by Middelburg spectacle-maker Hans Lippershey with the States General of the Netherlands on 2 October 1608 for his instrument "for seeing things far away as if they were nearby." [12] A few weeks later another Dutch instrument-maker ...
Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642), commonly referred to as Galileo Galilei (/ ˌ ɡ æ l ɪ ˈ l eɪ oʊ ˌ ɡ æ l ɪ ˈ l eɪ /, US also / ˌ ɡ æ l ɪ ˈ l iː oʊ-/; Italian: [ɡaliˈlɛːo ɡaliˈlɛːi]) or mononymously as Galileo, was a Florentine astronomer, physicist and engineer, sometimes described as a polymath.
Galileo's objective lens. Galileo's objective lens is a specific objective lens held in the Museo Galileo, Florence, Italy. It was used by Galileo Galilei in the Galilean telescope with which he discovered the four largest moons of Jupiter in 1610. The lens has a diameter of 38mm and a gilt brass housing.
Primary lens: The objective of a refracting telescope. Primary mirror: The objective of a reflecting telescope. Corrector plate: A full aperture negative lens placed before a primary mirror designed to correct the optical aberrations of the mirror. Schmidt corrector plate: An aspheric-shaped corrector plate used in the Schmidt telescope.
The telescope was designed to create a 3D map of billions of galaxies and other structures in the universe across space and time. The mission aims to peer back as far as 10 billion years into the ...
Galileo Galilei was an Italian scientist who is sometimes referred to as the "father of modern observational astronomy". [16] His improvements to the telescope , astronomical observations, and support for Copernicanism were all integral to the Copernican Revolution.
