WebThe index of refraction ranges from approximately 1.45 - 2 for visible materials and 1.38 - 4 for IR materials. In many cases, index of refraction and density share a positive correlation, meaning IR materials can be heavier than visible materials; however, a higher index of refraction also implies diffraction-limited performance can be achieved with fewer lens … WebOptical constants of C (Carbon, diamond, graphite, graphene, carbon nanotubes) Phillip and Taft 1964: Diamond; n,k 0.0354–10 µm Wavelength: µm (0.035424054–10.00000000) Complex refractive index ( n+ik) [ i ] Refractive index [ i ] n = 2.4168 Extinction …
