Use it in Lightsmith

Load this data in Python, simulate in one more line

pip install lightsmith

import lightsmith as ls

# E-FD13 (HOYA): E-FD13
hoya_e_fd13 = ls.fetch_refractiveindex("specs", "HOYA-optical", "E-FD13", ref="c5c2f188e848453def5970e347399d653df2ffc2")
print(hoya_e_fd13.range_nm)  # (365.01, 1013.98) nm
eps = hoya_e_fd13.eps([633])  # complex permittivity

Downloads the original record once (pinned to the imported snapshot) and caches it.

Any dataset here, as the library's Tabulated material (hoya-e-fd13/hoya).

# ... load hoya_e_fd13 as above, then:
sim = ls.Simulation(
    particles=[ls.Particle(shape=ls.Sphere(radius_nm=50), material=hoya_e_fd13)],
    medium_index=1.0,
    wavelengths=ls.WavelengthRange(start_nm=400, stop_nm=1000, num=81),
)
res = ls.solve(sim)  # exact Mie for a sphere
print(res.q_ext)     # extinction efficiency at each wavelength

Same spec runs with DDA, FDTD, BEM or T-matrix: ls.compare(sim, ["mie", "dda"]).
