Rutile ( TiO2) single crystal is one of the  most suitable materials for spectral prisms and polarizing devices such as optical isolators and beam displacers because it has a large birefringence with a high refractive index.   Compared to YVO4,  TiO2 crystal is more stable chemically and physically.   Our high quality rutile single crystal boule and polished components have been widely used for optical isolators and special prisms.
