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.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 2of equipment in this instrument is a lens called a half-shade device. To understand how a half-shade device works, let’s first imagine a simple polarimeter with only two polarizers, one fixed and one movable (the analyzer) (Figure A4.4). When unpolarized light is incident on the fixed polarizer, only those light waves
