Sapphire index of refraction

Index of Refraction for Sapphire

Index of refraction is also referred to as refractive index and refraction index.

No value is Ordinary ray in C-axis direction and Ne value is for Extraordinary ray perpendicular to C-axis. Birofrinqence (No-Ne) for sapphire is 0.008.
