The half-shade H goes between the polarized light source and the sample, and it consists of two half-disks of equally absorptive material. One half, ACB, is glass, and it lets the polarized light pass through unchanged. This video is about the construction and working of Laurent's half shade polarimeter. This will help you in understanding the concept and solve the problems .
When plane-polarised light passes through some crystals, the velocity of left-polarized light is different from that of the right-polarized light, thus the crystals are said to have two refractive indices, i.e. double refracting. Construction: The polarimeter consists of a monochromatic source S which is placed at focal point of a convex lens L. Just after the convex lens there is a N. Laurent’s Half-Shade Polarimeter. It is used for the measurement of the angle of rotation of optically active substance in solution. That is, angle through which the plane of .Together, the Laurent polarimeter with a half-shade plate allows for more accurate determination of optical rotation in substances.

To find the specific rotation of sugar solution by using Laurent’s Half Shade Polarimeter. Formula: The specific rotation of sugar solution is determined by the formula; S = θ / LC where ‘θ’ is the rotation produced in degree, L is the length of the tube in the decimeter (1 decimeter = 10 cm) and C is the concentration of the active . comparison, Laurent's Half-shade Polarimeter, Bi-quartz PolarimeterLaurent’s Half Shade Polarimeter It consists of two nicol prisms N 1 & N 2. N 1 is a polariser and N 2 is an analyser. N 2 is capable of rotation about a common axis of N 1 , and N 2. The rotation of analyser can be read on a graduated circular scale. Behind N 1 , .Polarimeter, Electric bulb with housing, sugar, balance, graduated cylinder and thermometer. . As shown in fig.1, Source is the Sodium Vapor lamp fitted in housing, P.Nicol, the polarizing Nicol, H, the Half shade device, A Nicol, the analyzing Nicol and Eye piece is the observing eye piece and solution is contained in the tube with glass end.
A polarimeter consists of two Nicols termed as polariser and analyser. These can be rotated about a common axis and the substance for which the rotation is to be determined, is placed in a tube in between these two. The half shade plate is placed between the polariser and the solution tube (cf., Fig. 3).
