Lead selenide (PbSe), or lead(II) selenide, a selenide of lead, is a semiconductor material. It is used for manufacture of infrared detectors for thermal imaging, operating at wavelengths between 1.5-5.2 µm.

For a typical sample of PbSe the refractive index and extinction coefficient at 632.8 nm are 4.9349 and 2.063402. 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".
