Sellmeier Equation
The Sellmeier Equation describes how the refractive index of a material—its ability to bend light—varies with the light's wavelength. Essentially, it predicts how light of different colors will travel through a material like glass or crystal. The equation uses specific constants related to the material’s properties to model this relationship. It’s widely used in optics to design lenses, lasers, and other optical devices, ensuring they perform accurately across various wavelengths. In simple terms, it's a mathematical tool that helps us understand and predict how light interacts with materials based on its color.
