Refractive Index of TiN, Titanium nitride

Titanium nitride (TiN) is an extremely hard ceramic material, often used as a coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.

For a typical sample of TiN the refractive index and extinction coefficient at 632.8 nm are 1.351 and 2.760. Below are files of complete refractive index and extinction coefficients. If the file is not available for download, you can request our proprietary file by clicking "Request".
