Thomas Hümmer, a doctoral student at the Ludwig-Maximilians-Universitat (LMU) Munich and Max Planck Institute of Quantum Optics, has been awarded €6000 for developing a highly sensitive microscope that explores the optical properties of nano-objects. The Nano Innovation Award is given for best innovative doctoral thesis. Hümmer's microscope uses two opposing mirrors whose light is reflected back and forth hundreds of thousands of times. If a nanoparticle is placed between the mirrors, its interaction with light will be strongly enhanced. This effect allows the detection of...Read full articleRelated content from Photonics MediaARTICLESUTA Engineer Earns NSF CAREER Grant to Develop Bioinspired 3D materialsKyungsuk Yum, an assistant professor at the University of Texas at Arlington, has been awarded a five-year, $500,000 National Science Foundation (NSF) Early Career Development Program grant to design...Photonics Spectra May 2019 IssueJuergen Czarske Receives OSA AwardThe Optical Society (OSA) has named Juergen Czarske of Technische Universitat Dresden (TU Dresden) the recipient of the 2019 Joseph Fraunhofer Award/Robert M.

A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookFlat Optics: Considerations When Buying: To simplify the process when purchasing flat optics, we will discuss the top six factors from a manufacturer’s perspective, all of which affect the three major areas of the purchasing decision: quality, delivery and cost.Flat optics generally perform three main functions: They transmit light (windows), reflect light (mirrors) and fold light (prisms).
