notes: label: Description
content: This Norremberg polariscope has a dark wood circular base with a circular mirror in the center. The two vertical brass rods hold an unsilvered glass mirror that is rotatable about a horizontal axis, and that has a small graduated circle indicating angle of inclination. There are two circular rings graduated in degrees, three holders for magnifying lenses (missing in this instance), and three analyzers: a Nichol prism, a black mirror in brass frame, and a stack of glass plates in a brass frame. The “E. Leybold’s Nachfolger / Mechanische Werkstatten / Cöln a/Rh” inscription on the base refers to a firm that began in business in 1850.
