The Theory of Birefringence PDF Cambridge Polymer Group

Quantitation of the colors seen in birefringent samples is commonly provided by means of the Michel-Levy chart illustrated in Figure 5 above. As is evident from this graph, the polarization colors seen in the microscope can be correlated with the actual retardation, thickness, and birefringence of the sample. The chart is simple to use with birefringent samples if you know two of the three
