Wooden Revolver Single Microscope, 1680

 

 

This Italian or Dutch late 17th-century wooden single microscope is contained in an oval case made of wood covered in tan leather, embossed with gold motifs. Objects to be viewed were held in the five holes within the circular revolving plate. The plate was turned to bring each object in view of the bi-convex little lens under the eyecup. As opposed to other microscopes of this general design, the lens was placed in fixed focus from the specimen wheel. The small holes in the revolver and the high magnification of the lens, suggest that this microscope was designed to observe Infusoria in water drops. The instrument fits into a shaped leather over the wood case with gold tooling on the outside and red inner velvet. The instrument is 18.5 cm long.

Although this device has no equivalent, in terms of design and method it is reminiscent of Dutch, French, and German Lands' microscopes of the type designed by Christian Huygens, Cosmus Conrad Cuno of Augsburg, Michael Butterfield, Nicolas Bion, Louis Chapotot, and Depovilly from Paris.
