Antique Direct Vision Spectroscope by Nachet of Paris c1900
Short Description
A fully functioning direct vision spectroscope by Camille Nachet of Paris in its original shagreen tube style case. The scientific method is after a design by Browning of London with alternating 3 flint glass prisms with 2 crown glass prisms. This pocket-sized spectroscope was often used to detect the Rainband a spectral effect that can be seen before impending rain. Handy if you are off in the country without a brolly.
Camille Sebastien Nachet 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 16 Rue Serpente, Paris. He was succeeded by his son Jean Alfred 1831-1908. Nachet is included with Chevalier and Oberhauser as the three leading optical instrument makers in Paris at this time.
