Polarized Light

Description

This apparatus is listed in the 1885 catalogue of Jules Duboscq of Paris as the “Grand Circle of MM. Jamin et Sénnarmont.” It was designed for the study of the laws of polarized light reflected from crystalline substances, from liquids and from metals. It could also be used to measure indices of refraction. With its accessories it cost 1000 francs (about $200). The circle is an early example of an ellipsometer, used to study the reflection of light at or near Brewster's angle.
