A polarimeter measures the direction and extent of the polarisation plane rotation. Depending on the type of instrument, the analyser is rotated manually or automatically until the maximum intensity of the light falls on the detector.
Polarimetry is used to analyze chiral substances and determine their concentration in solutions. It is applied in quality control, laboratory analytics, as well as in R&D in the pharmaceutical, cosmetics, chemical, food, and medical industries.
