About this video__In this video we will discuss about:-Laurent's half shade polarimeter which is used to measuring the optical rotation of optically active s. 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.
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).

Orient the polarimeter tube vertically with the end labeled 200 at the top; then, unscrew the cap at the top end being careful not to spill any liquidLAURENT’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 . Laurent's half-shade polarimeter[edit] When plane polarised light passes through some crystals,the velocity of left polarised light is different from that of the right polarised light thus the crystals are said to have two refractive indices i.e. double refracting Biquartz polarimeter[edit] In biquartz polarimeters, a biquartz plate is used.
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 document describes an experiment to determine the specific rotation of a sugar solution using a half-shade polarimeter. Various concentrations of sugar solution were tested between 0.025 g/cc and 0.4 g/cc. The specific rotation was calculated from the slope of a graph of the mean rotation angles versus concentration. The specific rotation of the sugar solution was found to .LAURENT’S HALF SHADE POLARIMETER Construction The essential parts of a Laurent’s half shade polarimeter are shown in Fig 1.10. S is a monochromatic source of light and L is a convex lens which renders the incident light in to a parallel beam, N1 and N2 are two Nicol prisms.
