TiO2
TiO2 is one of the most suitable materials for spectral prisms and polarization devices, such as optical isolators and beam displacers, because of its high refractive index birefringence. Compared with YVO4, TiO2 Crystal is more stable chemically and physically. High quality rutile single crystal rods and polishing components have been widely used in optical isolators and special prisms.
