Camille Sebastien Nachet (1799-1881) was a Parisian optician at the beginning of the 19th century. He began producing lenses for the famous microscope manufacturer Chevalier but later set up his own small business at the address Rue Serpente 16, Paris. He produced his first instruments based on the drum-type base models made previously by other manufacturers. He was succeeded by his son Jean Alfred (1831-1908). Nachet was included with Chevalier and Oberhauser as the three leading makers in Paris at this time.
