Advanced echelle grating fabrication The high-precision radial velocity spectrograph requires both high resolving power and wide spectral coverage, and achieving it requires a grating with a low groove frequency and high blaze angle so that most of the incident light is dispersed into high orders—to provide enough wavelength separation and sufficient signal intensity for high

MicroLED has long been seen as the future of direct-view displays because of its inherent characteristics, but the manufacturing cost and yield could delay or even cancel this outlook. That said, augmented reality (AR) glasses already account for the majority of microLED volume, as brightness requirements favor the technology. It also seems that the technology

Nitinol laser welding parameters Welding or joining nitinol is often necessary when manufacturing medical devices, surgical tools, or components for other industries with complex shapes or multiple parts—such as tubes, wires, and sheets, that can’t be produced from a single piece of material—to allow precise control of the final device geometry. Among the available joining

A multiquantum well (MQW) material created by Seth Bank, a professor of electrical and computer engineering, and his group at The University of Texas at Austin shows potential for nonlinear photonics applications. These engineered semiconductor heterostructures caught the attention of Pernille Undrum Fathi, a Ph.D. candidate in Federico Capasso’s group at Harvard University, and colleagues because

This episode features Eric Diebold, vice president and general manager for Instrumentation, Software, and Informatics at Waters Biosciences. He was also founder and CEO of Omega Biosystems, a startup based on his postdoctoral research on high-speed imaging flow cytometry. He talked recently with host Justine Murphy about Waters Biosciences and his role there, the innovations

Here’s the second of a two-part series featuring host Justine Murphy’s chat with Dr. Garrett Cole, an associate professor and the Nelson E. Claytor Endowed Chair in Optical Sciences at the University of Arizona’s Wyant College of Optical Sciences. In this episode, he talks about his numerous accomplishments and accolades, he reflects on his career

Space coatings don’t get a second chance. There’s no sending a satellite back to Earth to fix an underperforming mirror or filter, so every coating has to be built, documented, and qualified to hold its optical and mechanical performance for the entire mission — in vacuum, through thermal cycling, through atomic oxygen exposure in low
