JAKE SALTZMAN, NEWS EDITOR [email protected]Researchers from the Fraunhofer Institute for Applied Optics and Precision Engineering IOF (Fraunhofer IOF) and Friedrich Schiller University Jena developed an optical coating system that combines antifogging (AF) and antireflective (AR) properties. The dual-property technology could help boost the performance of lidar systems and cameras, such as those used in autonomous vehicles. “Walking into a warm room from the cold outside can cause glasses to fog up, blinding the user,” said research team leader Anne Gärtner from Fraunhofer IOF and Friedrich Schiller University...Read full articleRelated content from Photonics MediaArticlesUV-LED Photolithography Imparts Micro FeaturesTechnologies like integrated signal distributing, processing, and sensing networks require basic optical elements such as waveguides, splitters, gratings, and optical switches to be miniaturized....Photonics Spectra April 2024 IssueSuperhydrophilic Coatings Increase Efficiency of Solar CellsResearchers at the Fraunhofer Institute for Organic Electronics, Electron Beam, and Plasma Technology FEP (Fraunhofer FEP) produced hydrophobic, or water-repelling, surfaces that become...Photonics Spectra April 2023 IssueElectrochromic Smart Window Provides High Performance at Low CostResearchers at the Centre for Nano and Soft Matter Sciences (CeNS) and the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have fabricated a smart window that provides a low-cost...Photonics Spectra April 2023 IssueMicro-rings Make Green Gap Wavelengths Accessible for Tiny LasersCompact, high-quality lasers that generate red and blue light have been available for years, but lasers that emit light at yellow and green wavelengths and are small enough to fit on a chip have been...Photonics Spectra November 2024 IssueProductsLidar OpticsMeller Optics’ lidar optics can be fabricated to match specific military and commercial application requirements.
