It consists of a monochromatic source s which is placed at focal point of a convex lens l. A polarimeter is a scientific instrument used to measure the angle of rotation caused by passing. Laurents half shade polarimeter when planepolarised light passes through some crystals, the velocity of leftpolarised light is different from that of the rightpolarised light thus the crystals are said to have two refractive indices i. To find the specific rotation of sugar solution by using a polarimeter. Sodium lamp for half shade polarimeter and ordinary bulb or mercury lamp for biquartz polarimeter. For better accuracy in determination of specific rotation, half shade polarimeter is used which involves comparing the brightness of two halves in the field of view. Two types of polarimeters are generally used in the laboratory now a days. His fundamental striking articles at xamplified are easytounderstand and helpful enough for physicsphobic folks. Just after the convex lens there is a nicol prism p which acts as a polariser.
