Single Crystal Titanium Dioxide (TiO2), also known as Rutile, belonging to the Tetragonal structure, lattice constants a = 4.5937 Å, c = 2.9587 Å, TiO2 is often used to grow thin films of VO2, CrO2, SnO2, and β-Ga2O3. TiO2 substrates provide an excellent supportive platform for growing VO2 thin film which would otherwise be difficult to grow. Optical grade rutile titanium dioxide (TiO2) single crystal substrate has large birefringence, and a large refractive index, making it a good material for spectral prism and polarizing devices (such as optical isolators and beam splitters). Compared with YVO4, the TiO2 crystals have better physical and chemical stabilities.

Hangzhou Shalom EO offers TiO2 (Titanium dioxide) Crystals and Substrates with orientation error within ±0.5 degrees, and conventional thicknesses of 0.5mm and 1.0mm. These substrates feature a high-precision surface finish with a roughness of Ra<0.5nm, available in both single or double-surface polished versions (SSP or DSP).
