Norremberg Polariscope
notes: label: Description
content: Brass instrument on a square wooden base, with a rectangular mirror at the bottom, and vertical arch along which the instrument can recline at various angles. Above this is a horizontal circle that holds two brass rods that hold an unsilvered glass mirror in a brass frame that is moveable about a horizontal axis, a moveable stage with circular glass lens, and a Nichol prism analyzer in a graduated circle at the top. The “J. Duboscq / à Paris” inscription on this circle is that of Jules Duboscq (1816-1886), an important optical instrument maker who began in business around 1849. Dubosq referred to this form as a Norrenberg (sic) apparatus perfected by Wheatstone. The words “Ph. P. R. B. 12” are painted on the base; a tag on the bottom reads “STEVENS TECH 20660.”
