A collection of refractive-index spectra for some materials.
Details
The "generic_mspct" object contains "generic_spct"
objects with refractive index data.
The variables in each member spectrum are as follows:
w.length (nm)
n
k
Note
Data labeled "for unrestricted use" originate from the Filmmetrics
Refractive Index Database at
https://www.kla.com/products/instruments/refractive-index-database where
primary sources are provided. The names in refractive_index.mspct
are the same as in the downloaded files, except for the `.txt` tag.
