Photometer, c. 1870s, By Jules Duboscq a Paris
The photometer was used to measure the reflective and refractive properties of materials when placed in the side glass plates. Jules Duboscq (1817-1886) took over the instruments firm of his father-in-law Jean Baptiste Soleil in 1849. From about 1850-1860 the signature was Duboscq-Soleil. From about 1860-1885, Duboscq owned his own business, until in 1885 he became a partner with Philibert Francois Pellin (1847-1923).
