Rutile Titanium Dioxide Wafer TiO2 Single Crystal Substrate

Optical grade rutile titanium dioxide (TiO2) single crystal substrate. Rutile large birefringence, large refractive index, Which is A good materials for spectral prism and polarizing device (such as optical isolators and the beam splitter). Compared with YVO4, The TiO2 crystals has a better physical and chemical stability.
