Manual and Automatic Digital Polarimeters

Polarimeters are optical instruments utilizing polarized light. There are a great number of organic and inorganic substances “optically active” in their liquid or dissolved state. These substances are able to rotate in the direction of the oscillation of polarized light around a determined angle. This angle of rotation is measured by a polarimeter. Thus, a polarimeter will be used to determine the concentration of the optically active substance dissolved in an optically inactive liquid.
