RefractiveIndex

Provides an offline interface to refractiveindex.info.

Examples

julia> MgLiTaO3 = RefractiveMaterial("other", "Mg-LiTaO3", "Moutzouris-o")
Mg-LiTaO3 (Moutzouris et al. 2011: n(o) 0.450–1.551 µm; 8 mol.% Mg) - Polynomial

julia> MgLiTaO3(0.45) # default unit is microns
2.2373000025056826

julia> using Unitful

julia> MgLiTaO3(450u"nm") # auto-conversion from generic Unitful.jl length units
2.2373000025056826

julia> MgLiTaO3(450e-9, "m") # strings can be used to specify units (parsing is cached)
2.2373000025056826

julia> Ar = RefractiveMaterial("https://refractiveindex.info/?shelf=main&book=Ar&page=Peck-15C")
Ar (Peck and Fisher 1964: n 0.47–2.06 µm; 15 °C) - Gases

julia> Ar(532, "nm")
1.0002679711455778

In the case of database entries with multiple types of dispersion data (e.g. both raw dispersion data and dispersion formula coefficients), a vector of RefractiveMaterials is returned for each data type:

julia> RefractiveMaterial("glass", "HIKARI-F", "F1")
2-element Vector{RefractiveMaterial}:
 HIKARI-F (F1) - Polynomial
 HIKARI-F (F1) - TabulatedK

The database is currently limited to dispersion and extinction ('n-k') data. Future versions of the package may include the new n₂ (nonlinear index) database - please file an issue if this functionality is important to you.
