Spherical Aberration Simulator — Paraxial vs Marginal Focus
Geometrical Optics & Lenses
Visualize third-order spherical aberration in a plano-convex lens. Adjust radius, index and ray height to compute the axial focus shift via the Seidel formula.
Total Internal Reflection Simulator — Critical Angle and Evanescent Wave
Geometrical Optics & Lenses
When light goes from a high-index medium to a low-index medium and exceeds the critical angle, it totally reflects and an evanescent wave leaks across the interface. Var…
