Description of Rutile Titanium Dioxide Crystal Substrate

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