A polarimeter [1] is a scientific instrument used to measure optical rotation: the angle of rotation caused by passing linearly polarized light through an optically active substance. [ 2 ] Some chemical substances are optically active, and linearly polarized (uni-directional) light will rotate either to the left (counter-clockwise) or right .
A polarimeter is an optical instrument with which one can accurately measure the angle by which the polarization of light is rotated e.g. when it passes through an optically active medium (containing chiral molecules). Operation Principle of Polarimeters.
