- Problem Statement
- I have synthesize a material used in optical transmission. I want to know its transmission constant beta and its higher derivative. So the first step is to use the Sellmeier equation to describe its refractive indices. And I have already tested a series of refractive indices value at different wavelengths. How to get ist Sellmeier equation ?

- Relevant Equations
- $$n=\sqrt{1+\frac{B_1}{\lambda^2-C_1}+\frac{B_2}{\lambda^2-C_2}+\frac{B_3}{\lambda^2-C_3}}$$
