In optics, Keller cone or Rubinowicz–Keller cone is the locus of conically diffracted rays produced when an incident optical wave strikes a sharp edge of a scattering object. Named after American mathematician Joseph Keller, who reported the effect as an integral part of his geometrical theory of diffraction in 1962, it was first recognized by Adalbert Rubinowicz in 1924 for the special case of diffraction from an aperture on a thin screen.
