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.
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.
