BELLINGHAM, Wash., July 8, 2014 — Wei Zhang of the National University of Singapore and Hans Zappe and Andreas Seifert of the University of Freiburg in Germany have been awarded the Rudolf Kingslake Medal and Prize for their work on tunable liquid-filled microlenses. Their 2013 paper on the topic details a new, simplified fabrication process that uses polyacrylate as a membrane material. The microlenses could be used in solid-state linear actuators for scientific or industrial applications. The Kingslake Medal is awarded annually to an original paper in Optical Engineering, published by SPIE, the international society for optics and photonics, and includes a $2000 honorarium.
