1618584974Code 6998A Antique tacheometerCleps tacheometer Grande model, signed Ing. A. Salmoiraghi Milano n. 11448 of burnished brass and bronze, from the second half of the 19th century. Powerful instrument for topography, used from triangulation to detail detection, capable of approximations up to a thousandth of a degree, closed horizontal circles and reading by means of microscopes. It is a topographic instrument used for the direct measurement of azimuth and zenith angles and also used for the calculation of distances. Good condition, original patina. In perfect working order. Height 35 cm - 14.5 inches, telescope length 37 cm - 13.7 inches.

After having stayed and worked in different locations, in Piedmont, in Paris and Florence, Ignazio Porro (1801-1875), well-known scientist, professor of optics, inventor and precursor in the field of wide-angle lenses, settled in Milan and began teaching at Polytechnic. In Milan in 1865 he also founded a school-workshop specialized in the construction of topographic instruments together with Alessandro Duroni, pioneer of Italian photography, with the name of Filotecnica. On the death of Duroni, in 1871, Angelo Salmoiraghi, a pupil of Porro, already a very young soldier during the third war of independence against the Austrians, entered into society with his master and in 1877, after the Porro's death he bought the factory, which took the name of La Filotecnica Ing. A. Salmoiraghi, expanding its product range, producing mathematical instruments for drawing, astronomy, meteorology and navigation; the company builds, among other things, the first Italian sewing machine. During the First World War, it supplied war instruments, mainly aeronautics, and created a camera for aerial photography. In 1927 the company took the name of La Filotecnica Ing. A. Salmoiraghi S.A.. In 1939 Angelo Salmoiraghi died. During the Second World War a large part of the production was dedicated to war equipment and the company was therefore considered a war target: the factories are bombed, but at the end of the conflict the company manages to recover immediately. In the '70s it was bought by Dollond & Aitchinson, together with the firm Viganò, and became the Salmoiraghi Viganò, which in 2017 became the property of Leonardo Del Vecchio's Luxottica.
