Refractive index of some oxide and fluoride coating materials

Abstract

Spectroreflectometry was used to measure the refractive index of the following optical coating materials: Ta(2)O(5), HfO(2), Y(2)0(3), La(2)O(3), ZrO(2), CeO(2), CeF(3), LaF(3), NdF(3), MgF(2) in the 250-2000-nm spectral range.
