利用棱镜耦合反射率装置，测量了金红石（TiO_2）的寻常折射率和非常折射率随温度和波长的变化关系，测量范围分别为30-160 °C和454-1330 nm。测量已经完成了关于准确已知的一致的铌酸锂基板的指数。以与作为参考的衬底相同的精度给出折射率值，即，室温下±0.001，160 °C下±0.003。室温值与其他工作人员先前公布的值一致。Sellmeier方程，其中包括波长和温度作为变量的研究范围内给出的两个指数。
The ordinary and extraordinary refractive indices of rutile (TiO2) have been measured as a function of temperature and wavelength within the ranges 30–160 °C and 454–1330 nm, respectively, by using a prism coupling reflectivity setup. The measurements have been done with regard to the accurately known indices of a congruent LiNbO3 substrate. The index values are given with the same accuracy as that of the substrate taken as reference, i.e., ±0.001 at room temperature and ±0.003 at 160 °C. The room temperature values are coincident with those previously published by other workers. Sellmeier-like equations which include wavelength and temperature as variables within the studied ranges are given for both indices.
