Portable, handheld devices consume little energy, but can deliver targeted light that renders common pathogens harmless.RAJUL RANDIVE, CRYSTAL ISThe Centers for Disease Control and Prevention (CDC) reports that one in every 25 hospital patients in the U.S. will contract a hospital-acquired infection (HAI) during their visit. Recent CDC reports show that progress is being made in HAI prevention, but there is still more work to be done. One opportunity to address the remaining gap in HAI reductions is to automate steps in the current point-of-care hygiene protocol with UV-enabled devices or by integrating ultraviolet C (UVC) disinfection with existing health care equipment. Medical equipment makers are leveraging much smaller...Read full articleRelated content from Photonics MediaARTICLESThe Pandemic Is Driving Innovative Microfluidic Disease DetectionAs medicine and the monitoring of health have advanced into the modern era, researchers and clinicians have sought to capture an ever-increasing number of the biomarkers that are carried in...BioPhotonics Mar/Apr 2022 IssueLEDs and Optical Filters Expand Live-Cell Imaging CapabilityThe light source of a wide-field fluorescence microscope is often overlooked by scientists who perform live-cell imaging experiments.

The color of the emitted light depends on the semiconductor material and composition, with LEDs generally classified into three wavelengths: ultraviolet, visible, and infrared.The wavelength range of commercially available LEDs with single-element output power of at least 5 mW is 275 to 950 nm. Each wavelength range is made from a specific semiconductor material family,...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. For example,...Photonics HandbookMicroscopy Illumination: Considering Nonlaser Light Sources: Metal halide and LED light sources are changing the illumination landscape in microscopy. Brighter, easier to use and growing in application, they are driving new options in fluorescence, conventional bright-field and other contrast techniques.As recently as five years ago, shopping for a microscope light source was fairly straightforward. For routine applications, it was tungsten halogen, typically 100 W, while for fluorescence, it was an...Photonics HandbookIntegrating Spheres: Collecting and Uniformly Distributing Light: The integrating sphere is a simple, yet often misunderstood, device for measuring optical radiation.An integrating sphere’s function is to spatially integrate radiant flux (light).
