WebThe Michel-Lévy Color Chart can be used to determine the unique Birefringence number of an unknown crystalline sample when its thickness is known (measured) and the interference color noted. Steps: 1) Cross polarizer and Analyzer 2) Insert Full-Wave Red plate with the slow axis set at 45° to the Transmittance angle of the Polarizer. WebA relationship between interference color and retardation can be graphically illustrated in the classical Michel-Levy interference color chart, which plots retardation on the abscissa and specimen thickness on the ordinate. Birefringence is determined by a family of lines that emanate radially from the origin, each with a different measured value of birefringence …
WebThe colors in the Michel-Levy chromatic chart are classified into different orders in successive multiples of landas (Piegari and Flory 397). The first order is made up of black, gray, yellow, orange, and red according to their retardations.
