In the beginning, Nachet made lenses for the famous microscope maker Chevalier; but soon he opened his own microscope workshop in Rue St. Severin 16, Paris. His first instruments had the same design as popular drum microscopes made by other manufacturers. In the mid-19th century (circa 1850) Nachet was succeeded by his son Alfred and the company was renamed Nachet et Fils. Nachet was once considered one of the three leading microscope and lens manufacturers of Paris, together with Chevalier and Oberhauser.
