Rutile (TiO2) crystal has large birefringence and refractive index, is an ideal material for spectral prisms and polarization devices (e. g., optical isolators and beam splitter). Rutile (TiO2) crystal has better physicochemical stability than YVO4. OST Photonics offers high quality TiO2 substrates for researchers and industries. Crystal orientation, size and thickness can be customized according to your requirements...
