Crate use_optics 

use-optics

Small wavelength and spectral helpers for RustUse.

use-optics provides visible-spectrum boundaries, wavelength classification helpers, and a compact SpectralSample value type for lightweight optical calculations.

What this crate provides

Item	Purpose
SpectralBand	Ultraviolet, visible, and infrared classification
VISIBLE_MIN_NM / MAX_NM	Visible-light range constants
classify_wavelength_nm()	Wavelength band classification
wavelength_to_frequency_hz()	Frequency helper for a wavelength in nanometers
SpectralSample	Small wavelength-plus-intensity value type

Installation

[dependencies]
use-optics = "0.1.0"

Example

use use_optics::{is_visible_wavelength_nm, SpectralSample, SpectralBand};

let sample = SpectralSample::new(450.0, 0.8);

assert_eq!(sample.band(), Some(SpectralBand::Visible));
assert!(is_visible_wavelength_nm(sample.wavelength_nm));

Scope

• Wavelength-first helpers.
• Small immutable values.
• No polarization, interference, or rendering pipeline yet.
