Rice University researchers have developed a metalens that transforms incoming longwave UV light (UVA) into a focused output of vacuum UV (VUV) radiation. VUV is used in semiconductor manufacturing, photochemistry, and materials science. Historically it has been costly to work with, in part because it is absorbed by almost all types of glass used to make conventional lenses. The team led by Naomi Halas, the Stanley C. Moore Professor in Electrical and Computer Engineering and a professor of biomedical engineering, chemistry, and physics at Rice University, developed a metalens that...Read full articleRelated content from Photonics MediaARTICLESPhotonic Crystal Generates VUV Light at Wavelengths Suitable for SpectroscopyResearchers at the University of Tokyo have created a tabletop device that efficiently generates circularly polarized vacuum ultraviolet (VUV) light using an ultrathin film with nanoscale...Photonics Spectra October 2020 IssueFour-wave Mixing Approach Generates Narrowband EUV Light with LaserA method of modifying the spectral width of extreme ultraviolet light (EUV) has been developed by researchers at the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy.

A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot.
