The ordinary and extraordinary refractive index of two samples of sapphire, which differed in the way each was grown, was measured. The measurements were made over a wavelength range of 477-701 nm and a temperature range of 20-295 K. A three-term Sellmeier dispersion equation was fit to the data to permit refractive-index interpolation within several parts in 10(4). The data of index versus temperature were fit to a model and the results of dn/dT versus temperature are given along with certain physical constants that were extracted from the model.
测量了通过不同生长方式得到的两个蓝宝石样品的常折射率和非常折射率。测量在波长范围477 - 701 nm以及温度范围20 - 295 K内进行。用一个三项Sellmeier色散方程拟合数据，以便在10的4次方分之几的精度内进行折射率插值。将折射率随温度的数据拟合到一个模型，并给出了dn/dT随温度的结果以及从该模型中提取的某些物理常数。
