Rutile (Titanium dioxide) single crystal has a very high refractive index and birefringence.<\/p>\n

\"\"<\/p>\n<\/div>\n

\n

\"\" \"\" Birefringence: Rays passing through a rutile prism are separated into ordinary and extraordinary rays.
The polarization state of the extraordinary ray is perpendicular to that of ordinary one.
Please use our rutile for prism and birefringent polarizer with a high refractive index.<\/p>\n

Rutile has excellent resistance to heat and corrosion.
We provide high quality crystals grown by our original method.
Please do not hesitate to contact us for special specifications such as shape, size, and coating.<\/p>\n<\/div>\n
