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.Laurent’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 .
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.
The half-shade device is a lens divided into two halves that allows us to make a side-by-side comparison of light intensities.

The principles of the Laurent half-shade polarizer are well explained in this tutorial. In essence, the polarimeter consists of a collimated linearly polarized light source (S, L and P) that is passed through the sample .
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 .Half shade principle Optical rotatory power Optical activity Specific rotation Aim of the experiment To determine the specific rotation of an optically active substance by polarimeter. Apparatus required A Polarimeter Optically active substance (known weight) A measuring cylinder A beaker A scale Distilled water Sodium light source Theory
The optical activity of a substance is measured by its specific rotation (or specific rotatory power).. 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 substance in gm/cc in the solution.
POLARIMETERThe Polarimeter consists of Monochromatic source of light usually a sodium lamp. This light is allowed to pass through a narrow slit and then to N.

laurents half shade polarimeter (1) - Free download as PDF File (.pdf), Text File (.txt) or read online for free. This document describes a procedure to determine the specific rotation of sugar using a Laurent's half shade polarimeter. Key steps include: 1) Cleaning and filling a polarimeter tube with a sugar solution of known concentration 2) Passing plane-polarized light . Editor's Notes. Some chemical substances are optically active, and polarized (unidirectional) light will rotate either to the left (counter-clockwise) or right (clockwise) when passed through these substances. The amount by which the light is rotated is known as the angle of rotation. . Laurent's half-shade polarimeter[edit] When plane .
LAURENT’S HALF SHADE POLARIMETER. •One half of the incident light passes through the quartz plate ACB and the other half through ADB •On passing through the glass, half the vibrations will remain along OP •On passing through the quartz half, the vibrations split into e- and o- rays •O –vibrations are along OD and e-vibrations are .position inside the polarimeter. Switch on the source of light and look through the eyepiece. • In case of half shade polarimeter, two halves of unequal intensity is observed. Left half may be bright and the right half may be dark, or vice versa. By rotating the analyzer eyepiece system,
