Modification of the brice light‐scattering photometer for photoelectric polarimetry by the rouy method

Construction details for modifying the Brice light-scattering photometer for use in photoelectric polarimetry have been given. The measuring technique is based on the Rouy method, which is perhaps the most sensitive of all photoelectric methods of measuring the optical rotation of liquids, especially at small angles. A standard deviation of 0.01° has been observed with the use of an instrument modified in this way.
