Use it in Lightsmith

Load this data in Python, simulate in one more line

pip install lightsmith

import lightsmith as ls

# SiO2 - Fused silica (infrared grade) (CRYSTRAN): SiO2 - Fused silica (infrared grade)
mat = ls.fetch_refractiveindex("specs", "CRYSTRAN-optical", "fused_silica-ir", ref="c5c2f188e848453def5970e347399d653df2ffc2")
print(mat.range_nm)  # (200, 3370) nm
eps = mat.eps([633])  # complex permittivity

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

import lightsmith as ls

url = "https://materials.lightsmith.dev/v1/datasets/ds_16bd0f4992e8/lightsmith"

print(mat.source)  # citation and provenance travel with the data

Any dataset here, as the library's Tabulated material (crystran-fused-silica-ir/crystran).

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