Therefore, in (Blend)LuxCore, the correct way to input values is to set the Cauchy-A coefficient as IOR, and the Cauchy-B coefficient as dispersion. For artistic applications, it should be fine to use the IOR at a visible wavelength instead of the Cauchy-A term. ... The Figure below shows an example plot for N-BK7 ...
In its original and the most general form, the Sellmeier equation is given as , where n is the refractive index, λ is the wavelength, and Bi and Ci are experimentally determined Sellmeier coefficients. These coefficients are usually quoted for λ in micrometres. Note that this λ is the vacuum wavelength, not that in the material itself, which is λ/n. A different form of the equ… WebWe conclude with a catalog of refractive indices and Sellmeier coefficients of the measured liquids and show the location of the analyzed materials in an Abbe diagram.
