Exp- To Measure optical rotation of optically active substances e.g. Sugar.
PHYSICS, Class XII, Part - 2, Chapter - 10, Wave optics.
It is a kind of instrument for measuring the optical rotation of optically active substances e.g. Sugar. The unit is mounted in a steel box. A 6V bulb present in the base works as a source of light. Light passes through a polarising filter and again through yellow filter to the sample tube. Rotation of the polarised light can be measured by rotatable analyser which is mounted in the top panel with a fixed 0-360° scale. The sample tube may be taken out for sample keeping purpose. Suppled with polarisers, yellow filter and sample tube.
