Digital Polarimeter
A digital polarimeter is a scientific instrument used to measure the angle of rotation of polarized light as it passes through optically active substances. It consists of a light source, polarizer, sample tube, analyzer, and detector. The sample tube holds the substance being tested, and the polarizer and analyzer are positioned in such a way that the intensity of light passing through the sample can be measured at different angles. By analyzing how the intensity changes with angle, the polarimeter can determine the angle of rotation caused by the substance's optical activity.
