Description :
The polarimeter is a kind of instrument for measuring the optical rotation of a substance. It can be used to analyse the concentration, content & purity of substance. The light beam from the light source passes through the illuminating lens & filter and it becomes collimated polarized. The polarizer produces a triple shadow field on the ½ wavelength plate. The optical rotation can be measured through an optically active substance (sugar solution).
