Spectral geometric optics
Move a prism, lens or mirror and watch separate wavelengths take different paths. This optical bench emphasizes intuition: exaggerated dispersion makes spectral transport, reflection, refraction and total internal reflection easy to follow one interaction at a time.

- λ
Sample the spectrum
Represent a broad source with wavelength-labelled rays.
- n(λ)
Bend the path
Wavelength-dependent refractive index changes each transmission direction.
- ↗
Split the energy
Follow reflected and transmitted contributions through the optical bench.
- ▥
Read the arrivals
See how geometry separates the spectrum at the sensor.
Color can change the path itself, providing an intuitive foundation for the larger spectral renderers.
