摘    要:冰洲石晶体的主轴折射率随波长变化而变化。本文通过对Sellmeier方程严格求解.得出其系数表达式。经验证,折射率的计算值与实验值十分吻合。通过线性插值的方法求解出不同波长的温度系数表达式.从而得出不同温度不同波长的冰洲石晶体的主轴折射率,得到Sellmeier方程常数在各温度下的常数值。

关 键 词:冰洲石晶体  色散  Sellmeier方程  温度系数

Abstract:The refractive index of the calcite varies with the wavelength. With strict solution,the thesis gains the expression of the coefficient for the Sellmeier equation. It agrees with the experimental results well. The expression of the thermo-optical coefficients at the different wavelengths are got by linear interpolation aloorithm.And it can yield the refractive indices of the calcite at different temperature and different wavelengths through it. Then those can get the constants of the equation at different temperature.
Keywords:calcite crystal  dispersion  Sellmeier equation  temperature coefficients
