polarimeter




polarimeter
The plane of polarization of the sodium light from the polarizer is rotated as it passes through a solution of optically active substances such as sucrose. The extent of the rotation is determined by rotating the analyzer until no light reaches the observer. The slits in the analyzer are then at right angles to the final plane of polarization.

An instrument used in polarimetry which uses two Nicol prisms, one fixed (the polarizer) and one rotatable (the analyzer), with the sample between them, to measure optical activity and other aspects of polarization.
