Caustic Projections

Caustic Projections: the intricate geometries of light due to refraction through various curved surfaces of transparent plastic. A 520 nm green laser pointer is refracted trough a sample optical element with surface features of triangle and square pyramids and convex lens elements- made to exhibit examples for lighting applications. When light rays refract through a curved surface they concentrate into bright patches called caustics, often with cusp singularities (sharp points) and intricate threads of shadow. ➡ Follow the link in my profile for info on where to get this and other amazing items featured here on @physicsfun #physics #physicstoy #optics #opticalelements #caustics #laser #laserpointer #refraction #lightrays #science #scienceisawesome
