Refractive Index of CdTe, Cadmium Telluride
Cadmium telluride (CdTe) is a crystalline compound formed from cadmium and tellurium. It is used as an infrared optical window and a solar cell material. It is usually sandwiched with cadmium sulfide to form a p-n junction photovoltaic solar cell.
For a typical sample of CdTe the refractive index and extinction coefficient at 632.8 nm are 2.982 and 0.350. 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".
