Researchers from ETH Zürich have developed a technique to produce complex glass objects with 3D printing. The method is based on stereolithography, one of the first 3D-printing techniques developed during the 1980s. The researchers developed a special resin containing a plastic and organic molecules to which glass precursors are bonded. The resin can be processed using commercially available digital light processing technology, which irradiates the resin with UV light patterns. Wherever the light strikes the resin, it hardens because the light-sensitive components of the polymer...Read full articleRelated content from Photonics MediaARTICLES3D Printing Offers Versatility in Optical DesignResearchers at Lawrence Livermore National Laboratory (LLNL) used multimaterial 3D printing to develop tailored gradient refractive index glass optics, delivering a result that could enable the...Photonics Spectra February 2021 IssueETH Team Leads Way to More Precise Diffraction GratingsFor decades, scientists have tried to improve the design and production of diffraction gratings, one of the oldest and most important technologies for controlling light.

Mechanical noise, for example, can obscure high-resolution images and affect the quality of nanotechnology processes. Fortunately, vibration can be controlled through proper experimentation, process design, and the use of specialized equipment.In general, there are three common approaches to reducing mechanical excitation of photonic systems. The first is identifying the sources of vibration and implementing ways to eliminate or reduce...Photonics HandbookThin-Film Coatings: A Buyers' Guide: The vast majority of optics used in precision scientific, industrial, biomedical, and military applications incorporate thin-film coatings on their surfaces. Therefore, it’s useful for almost anyone involved in the specification and purchase of optical components to have some familiarity with the typical performance characteristics, trade-offs and limitations of various coating types, as well as some knowledge of the capabilities of common thin-film production technologies. This article provides an objective overview of both these topics.What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied.
