An optical apparatus designed for the mapping of binaryor ternary phase diagrams is described. A polychromatic polarizedlight illuminates a sample and the rotation of its polarization ismeasured with a spectrometer for various magnetic fields. Themeasured parameters are the natural and magnetic rotatory power ofthe sample which allow the concentration retrieval of everycompound to be done. Results show that the apparatus issuitable for correct positioning of single phase boundary on theternary water - n-dodecyl-β-d maltoside - sodium chloridesystem.
