A polarimeter is an optical instrument with which one can accurately measure the angle by which the polarization of light is rotated e.g. when it passes through an optically active medium (containing chiral molecules). Operation Principle . 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.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.

This video describes method to analyse a light ray for its polarization state, the optical activity, and construction and working of Lorentz half shade pola. A polarimeter works on the principle of optical rotation, which is the rotation of the plane of polarization of light as it passes through certain materials. When polarized light passes through a substance that has a different refractive index for right and left circularly polarized light, the plane of polarization of the light rotates.
LAURENT’S HALF SHADE POLARIMETER. •The half wave plate introduces a phase difference of rad between the two vibrations •The resultant vibration will be along OQ whereas the vibrations of the beam emerging from glass plate will be along OP •The half wave plate turns the plant of polarization of the incident light through an angle 2About.
