Titanium Oxide TiO2 Crystal Substrates

  • $ 6500

High purity (>99.9%) Rutile TiO2 single crystal substrates with epi-ready surface polish are widely used as substrate materials for thin film growth and depositions. Rutile phase Titanium Oxide (TiO2) single crystal is one of the most commonly used materials for optical isolators and special prisms. This is because Rutile TiO2 has a large birefringence with a high refractive index.
