Caustic Projection Optical Element: the intricate geometries of light due to refraction through various curved surfaces of transparent plastic. A 488 nm cyan laser pointer is refracted through an optical element with lumpy surface features which create this aurora/nebula effect. 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 #physicsfun #additiveoptics #opticalelements #caustics #laser #laserpointer #refraction #lightrays #science #scienceisawesome
