Refractive-index spectra for materials

Description

A collection of refractive-index spectra for some materials.

Usage

refractive_index.mspct

Format

A "generic_mspct" object containing multiple "generic_spct" objects.

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.filmetrics.com/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.

Examples

length(refractive_index.mspct)
names(refractive_index.mspct)
refractive_index.mspct$PMMA # acrylic or Plexiglas
refractive_index.mspct[["PMMA"]]

# Compute spectral reflectance for an interface between acrylic and air
# incidence angle of colimated light 60 degrees away from the normal.
