Refractive Index of Co, Cobalt

Cobalt is a hard, lustrous, gray metal. It is used in the preparation of magnetic, wear-resistant, and high-strength alloys.

For a typical sample of Co the refractive index and extinction coefficient at 632.8 nm are 2.817 and 4.310. 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".
