Description
Here, a hollow brass tube (13 inches long) sits atop a brass stand (15 inches high). At one end of the tube is a glass mirror that can be aimed in various directions. At the other is an eyepiece with an analyzer, and a graduated circle. The “Soleil Fils Opticien / Rue de l’Odéon No 35 à Paris” inscription on the side of the tube refers to J. B. F. Soleil, an optical instrument maker who opened a shop at this address in 1825 and who, for a while, used the term “Fils” to distinguish himself from his father, who also made optical instruments. The U.S. Military Academy bought this instrument between 1834 and 1844.
This form was often associated with the French physicist, Jean-Baptists Biot.
