Use it in Lightsmith

Load this data in Python, simulate in one more line

pip install lightsmith

import lightsmith as ls

# IVG540 (ISUZU): IVG540
isuzu_ivg540 = ls.fetch_refractiveindex("specs", "ISUZU-filter", "IVG540", ref="c5c2f188e848453def5970e347399d653df2ffc2")
print(isuzu_ivg540.range_nm)  # (200, 2000) nm
eps = isuzu_ivg540.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 (isuzu-ivg540/isuzu).

# ... load isuzu_ivg540 as above, then:
sim = ls.Simulation(
    particles=[ls.Particle(shape=ls.Sphere(radius_nm=50), material=isuzu_ivg540)],
    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"]).
