JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]Researchers at the University of Tokyo have developed a technique to drastically increase the speed of infrared spectroscopy. The technique, called time-stretch infrared spectroscopy, surpasses dual-comb spectroscopy nearly 10× over. The research could enable observation of very quick chemical reactions, as well as new applications in high-speed imaging or label-free flow cytometry. “I have worked on developing dual-comb spectroscopy for a while and noticed its advantages and disadvantages, and realized that we need another technique to improve its measurement speed with...Read full articleRelated content from Photonics MediaArticlesEUV Light Source Could Meet Chip Makers’ Future Lithography NeedsScientists from Helmholtz-Zentrum Berlin (HZB), Tsinghua University, and Germany’s national metrology institute Physikalisch-Technische Bundesanstalt (PTB), are building the foundation for a...Photonics.com 7/2/2024DUV Laser Design Enhances Lithography PerformanceArgon-fluoride (ArF) excimer lasers — deep UV (DUV) lasers emitting light with a wavelength of 193 nm — are used in lithography to create precise patterns.
