This example demonstrates the flexibility of Optica. A lens
made of a polymer membrane is modeled. The membrane seals a chamber
with a pressure higher than the environment and is therefore deformed.
A ray traversing the flexible lens passes a window, the pressure
fluid and the membrane.
This example uses Optica to model the optical behavior of a
diamond solitaire gem with 58 facets as it scatters rays of light.
The colors indicate the amount of energy present in each ray on a
