Abstract
The rotation of the plane of polarization of incident light produced by reflection from a polished surface, cleavage, or crystal face of an anisotropic mineral changes as the immersion medium (oil, water, air) is varied. For a given mineral the changes produced are functions of the optical constants of the mineral and are therefore specific properties. This paper discusses the principles underlying changes in angles of rotation and related rotation properties with variation in the immersion medium and the possible applications of the changes to the study of minerals in reflected light. Preliminary observations suggest that the changes can be used as an aid in identifying ore minerals.
