This dataset is the Hugging Face friendly parquet export of the SpecFormer full-spectrum optical multilayer thin-film dataset. It contains 10,000,000 training samples, 500,000 validation samples, and 500,000 test samples. Each sample stores compact uint16 spectral targets together with padded structural labels and fabrication-related constraints for inverse design and spectrum-conditioned modeling tasks.
The 774-dimensional target is ordered as VIS-R, VIS-T, NIR-R, NIR-T, and normal-incidence IR emissivity. Spectral values are stored as `uint16` values scaled by 1000; divide by 1000 to recover normalized floating-point spectra in [0, 1].
