About. This experiment belongs to Engineering Physics IIT-Bombay. Full Name: Laurentz half shade polarimeter: To determine the specific rotation of optically active substanceLaurent's half-shade polarimeter. 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. . Just after the convex lens there is a Nicol Prism P which acts as a polariser .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.
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.
