John A. Hoffnagle and C. Michael Jefferson are presented with Rudolf Kingslake Medals by 2005 SPIE President Malgorzata Kujawinska for their paper, "Beam shaping with a plano-aspheric lens pair," published in the November 2003 issue of Optical Engineering, SPIE's journal. The paper was recognized for its innovative creation of a refractive beam shaper using two aspheric lenses to generate a flat-top beam substantially superior to a Gaussian beam for illumination applications. The Rudolf Kingslake awarded recognizes the most noteworthy original paper to appear in the journal on the theoretical or experimental aspects of optical engineering.
