Polarimeters measure the optical activity of a substance. This is done by passing polarized light through a substance and observing the angle of light emitted. Optically active substances will rotate the polarized light while non-optically active substances will have an angle of 0°. This technique was developed to identify and study enantiomers which share many chemical properties typically used to distinguish one molecule from another, but that can have significant effects in chemistry experiments, pharmaceuticals, and food quality. While the original polarimeters required manual adjustments to obtain a reading, today's digital polarimeters perform readings automatically and give instantaneous results.
