	Arcetri Oservatory - The Amici Telescope - At the 3rd Meeting of the Italian Scientists, held in Florence in 1841, Amici presented an objective lens with a diameter of 28 cm and a focal length of 5.3 m. This acromatic doublet, composed of a lens of crown glass and another of flint glass produced by the Guinand factory in Paris, was made in the workshop of the Museo by the mechanic Toussaint, under the supervision of Amici. It was later improved with a crown lens of better quality, and mounted on a mahogany tube. For about 40 years, the great refractor of Prof. Amici was the largest refracting telecope available in Italy.
