Refractive Index of Si3N4 (Si Poor)

Si-poor Si3N4. May also be used to model non-stoichiometric Si3N4 by measuring n and k.

For a typical sample of Si3N4 (Si Poor) the refractive index and extinction coefficient at 632.8 nm are 1.701 and 0.000. 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".
