Abstract
A machine for testing polarization rotation by translucent specimens includes a standard spectrophotometer disposed for establishing and converging a pair of light beams from a single monochromatic source and provided with a recorder. A polarizer, a station for mounting a translucent specimen and an analyzer are serially provided for passage therethrough of one of the beams and a magnetic device is provided for reversible mounting astride the station. The polarizer and analyzer are respectively disposed for orientation to a reference plane of the one beam and for modification of the intensity thereof in a plane displaced at a predetermined angle to the reference plane. The magnetic device displaces the specimen polarization plane at equal and opposite angles to the reference plane and the recorder provides outputs in logarithmic proportion to the intensity ratios of the beams.
