Hello.
Sellmeier coefficient is defined by
(in form of)
n^2 = constant + B1 wl ^2 /(wl^2-C1) + B2 wl ^2 /(wl^2-C2) +B3 wl ^2 /(wl^2-C3)
as written in Wiki
But in materials.py, Sellmeier equation is written by
Set the rix dispersion function to the 6-parameter Sellmeier
function as so:
n(wls) = 1. +
B1 wls 2 / (wls 2 - C1) +
B2 wls 2 / (wls 2 - C2) +
B3 * wls 2 / (wls 2 - C3)
Sellmeier is about to "the square of refractive index" but the comments in the Method describe it as "the refractive index" itself.
I checked
def __from_sellmeier(n0_smcoeffs, wls)
I can see the script is right but the only description is wrong.
So the description should be updated correctly.
