Polarimeter is an instrument used to determine the rotation of a substance, and its working principle is based on the rotation of polarized light. By measuring the rotation angle of the sample to the polarized light, the concentration, content and purity of the substance can be analyzed and determined. Natural light through the polarizing mirror to produce plane polarized light, when the tube is filled with optical substances, polarized light through the material solution, the angle of polarized light will rotate to the left or right a certain angle. In order for the polarized light rotated at a certain angle to pass through the polarizer grating, the polarizer must be rotated at a certain angle so that the brightness can be seen at the eyepiece. This angle of rotation is the rotation of the solution of the substance to be measured
