Researchers from the Singapore University of Technology and Design (SUTD) and Southern University of Science and Technology (SUSTech) in China have proposed a fabrication technique that integrates oscillation-assisted digital light processing (DLP) 3D printing with grayscale UV exposure to render an ultrafast and flexible fabrication of microlens arrays with optical surface smoothness. Optically smooth microlens array is fabricated by an oscillation-assisted 3D-printing method. Owing to the mechanical oscillation applied on the projection lens, jagged surface induced by the gaps between...Read full articleRelated content from Photonics MediaARTICLESHigh-Spatial-Resolution Camera Achieves 15 Trillion Frames per SecondAn all-optical ultrafast imaging system developed by scientists at Shenzhen University has reached 15 trillion frames per second.
