Sellmeier Coefficients for the Refractive Indices of Calcite at Crystal Different Temperatures

The refractive index of the calcite varies with the wavelength.With strict solution,the thesis gains the expression of the corefficient 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.
