The light figure based method proposed recently for determination of the relative dispersion of the optical constants has been applied to the uniaxial material, CaCO 3, with accurately known refraction indices in a wide spectral range. The dispersion term determined directly from the spectral data for the ordinary refraction index and the term calculated from the approximation given by the light figure based approach coincide with high accuracy. Distribution of light intensity in light figures of 1.225×10 3μm thick CaCO 3 has also been measured and analyzed to ascertain the obtained value of the dispersion term. Agreement is very good. The use of the plate with known optical constants is shown to enable calibration of the deployed optical system. © 2002 American Institute of Physics. © 2002 American Institute of Physics.
