Filters for polarimeters

Polarimeter (Polarimeter) is an instrument for determining the optical rotation of optically active substances. By measuring the optical rotation of the sample, the concentration, content and purity of the substance can be analyzed and determined. Natural light passes through the polarizer to produce plane polarized light. If an optically active substance is contained in the light rotation tube, when the polarized light passes through the substance solution, the angle of the polarized light will rotate to the left or right by a certain angle. At this time, in order to allow the polarized light rotated by a certain angle to pass through the polarization analyzer grating, the polarization analyzer must be rotated by a certain angle to see bright at the eyepiece. The angle of rotation is the optical rotation of the solution of the substance to be measured.
