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. 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.8 Laurent's Half shade polarimeter V2 T Two nicols- N1 AND N2 Half shade device-H Telescope-T Glass tube-T1 V1 Nicol N2 can be rotated and its position can be noted on a circular scale with verniers V1 and V2 Monochromatic light after passing through N1 become plane polarized with its vibrations in principal plane of nicol.Laurent polarimeter A Laurent polarimeter is an instrument used in optics for measuring the rotation of plane-polarized light caused by optically active substances. Optical rotation, also known as optical activity, is a property of certain materials (like chiral compounds) to rotate the plane of polarization of light passing through them.

The principles of the Laurent half-shade polarizer are well explained in this tutorial [dead link; archived version].In essence, the polarimeter consists of a collimated linearly polarized light source (S, L and P) that is passed through the sample tube T (which will rotate the polarization if the sample is optically active), and then polarized (A) and seen through a .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 .
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.link of " biquartz polarimeter : part - 1 " video*****https://youtu.be/vpzrv5ipigclink of " laurent's half shade p.#polarimeter#howtofindspecificrotation#explainationoflaurent'shalfshadepolarimeter#explainationofconstructionandworkingofpolarimeter#whatisopticalactivity#dr.
Polarimeters come in different types including Laurent's half-shade polarimeter and biquartz polarimeter. A basic polarimeter consists of two crossed polarizers - polarized light from the first polarizer passes through the optically active substance, rotating the plane of polarization. The second polarizer then needs to be rotated to match this . Laurent’s Half-Shade Polarimeter has been authored by Prashant Sharma, a Technology Columnist-Engineer by Profession who has scripted a cluster of Utility focussed and simplistic write-ups relating to Physics out here.His fundamental striking articles at XAmplified are easy-to-understand and helpful enough for Physics-phobic folks.
