Load this data in Python, simulate in one more line

pip install lightsmith

import lightsmith as ls

# Au (Gold): Magnozzi et al. 2019: n,k 0.252–1.45 µm; 25 °C
au = ls.fetch_refractiveindex("main", "Au", "Magnozzi-25C", ref="c5c2f188e848453def5970e347399d653df2ffc2")
print(au.range_nm)  # (251.57, 1449.2) nm
