use-optics

Optics primitives for spectra, wavelengths, and visible-light boundaries.

use-optics is the natural optics sibling to use-color and use-wave. It starts with compact helpers for classifying wavelengths, working with visible-light ranges, and turning spectral data points into small Rust values.

The scope is intentionally narrow for v0.1: auditable wavelength primitives first, richer optical models later.

Usage

use use_optics::{classify_wavelength_nm, SpectralBand};

assert_eq!(classify_wavelength_nm(532.0), Some(SpectralBand::Visible));

Scope

• Visible-range helpers and spectral classification.
• Small wavelength-centric value types.
• No ray-tracing, lens design, or color appearance modeling yet.
