Coat glass with a film a quarter-wavelength thick and its two reflections cancel by destructive interference — an anti-reflection coating. It works best at one wavelength (the reflectance dips to near zero there), giving camera lenses and glasses their faint purple sheen. The same physics makes soap bubbles and oil slicks shimmer with color.

About this simulation
The full Thin-Film Coating tool models an optical fiber with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
