  • Patent number: 5504581
    Abstract: A phase plate is superposed on a sample, and this phase plate is so adjusted that the phase difference of the total retardation of the sample and the phase plate is integral times 2.pi. with respect to a measuring beam of a first wavelength, so that retardation can be correctly measured even if an order is increased. In this state, a measuring beam of a second wavelength which is approximate to the first wavelength is employed and two polarizing plates maintaining polarizing directions in parallel nicol relation are singularly rotated with respect to the sample which is arranged therebetween. The ratio Im/Io between maximum value Io and minimum value Im of currently transmitted light intensity is applied to a previously prepared relation between the order n of retardation and this ratio Im/Io to derive the order of retardation of the sample, to thereafter obtain correct retardation.

  • Patent number: 5406371
    Abstract: In order to efficiently obtain data for calculating retardation values at a plurality of wavelengths, a sample having birefringence is placed between a polarizer and an analyzer, which are maintained in a parallel nicol relation to each other and rotated about an optical axis of measuring light. White measuring light is applied through the polarizer so that the light being passed through the sample and transmitted through the analyzer is received by a polychromator. A one-dimensional optical sensor is arranged on an outgoing imaging surface of the polychromator, to simultaneously detect transmitted light intensity values of a plurality of wavelengths. Since transmitted light intensity values of a plurality of wavelengths are obtained every polarization rotation angle of the polarizer and the analyzer, it is possible to obtain dispersion of retardation values with respect to wavelengths and the like by processing the data.
