Browser-based instruments for the optical bench. Everything runs client-side.

143,786 NIST ASD lines, 549 species, 94 elements. Periodic-table selection, ionization-stage filters, zoomable spectra, line finder.

Pixel→wavelength polynomial fits (orders 1–6) in a numerically stable Chebyshev basis, with coefficient uncertainties, R², and residual plots.

IN DESIGN

LTE Boltzmann–Saha synthetic spectra with Voigt profiles and Stark widths. Awaiting the v2 NIST dataset (levels, A_ki, g_k, partition functions).
