Lens Ray Tracer
Interactive lab: Move the optics and discover why expensive cameras exist.
What is this?
A visual, interactive experiment about Lens Ray Tracer. Its main parameters update live and the simulation runs entirely in the browser.
How it works
Every surface obeys n₁sinθ₁ = n₂sinθ₂. Marginal rays through a spherical lens do not converge exactly with paraxial rays.
