Diamond absorption coefficient
Webspectral bands, because of absorption in the 8 μm to 14 μm LWIR band. The index of refraction for silicon is also large (n = 3.4255), as well as the refractive index change with temperature (dn/dT = 150 ppm/K). The dispersion is relatively low. It can be diamond turned, but it is difficult. 2.3 Zinc Sulfide WebOPTICAL PROPERTIES OF DIAMOND - jhuapl.edu
