Rutile ( TiO2) single crystal is one of the most suitable materials used 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 chemically and physically stable. Our high quality TiO2 (rutile) single crystal is grown by floating zone method and is an excellent choice to be used as optical compoments and epi thin film substrates.
