Room‐temperature refractive indices dispersion and anisotropy were measured in single Ca 0.28 Ba 0.72 Nb 2 O 6 (CBN‐28) crystal between 380 and 700 nm. The refractive index of Ca 0.28 Ba 0.72 Nb 2 O 6 are measured by the spectroscopic ellipsometry. The dispersion curves were fitted to different Sellemeier functions. The normal dispersions were observed. Using the interference of polarized light, the birefringence in the long wavelength region is obtained. The results are in good agreement with the reference. A new technique was used to analysis the experiment data and this technique is proved to be more simple and efficient. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
