Spectral data

Each emitter can expose measured spectral data through the public SDK.

The current public data model stores a list of samples. A sample has:

• wavelength
• measurement

The SDK sample shape is 380-780 nm at 1 nm intervals, for 401 samples when full visible-range data is present.

Rust

let emitter = source.emitters().await?.into_iter().next().unwrap();
let spectral_data = emitter.spectral_data().await?;

for sample in spectral_data.samples() {
    println!("{} {}", sample.wavelength(), sample.measurement());
}

Export JSON

enody download-spectral-data -o spectral-data.json

The JSON export is useful for reproducible experiments, notebooks, and integrations that do not need a live device connection.

Tensor conversion

Rust tools can use the JSON export or direct spectral samples as input to their own matrix representation. Python and JavaScript wrappers also expose tensor helpers for language-specific optimization workflows.

This makes spectral optimization a regular tensor problem: choose emitter weights, multiply by measured emitter spectra, compare the mixed spectrum to a target, and update the weights.
