TiO2 Substrates

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.


Application of TiO2 Substrates


  • Spectral prisms

  • Optical isolators

  • Beam splitter


Advantages of TiO2 Substrates
