LED Driver for High Power Machine Vision Flash
Automation is nothing new and its demands are rapidly increasing, either in production or inspection. More sensors are used and many are based on direct or reflected light detection. Some work in the visible range and others work in the non-visible spectrum of light. LED lighting has become the standard in most applications as the solid-state light source offers numerous advantages over other lighting technologies. However, the LED lighting system is only as good as the peripheral components and LED drivers are one key element in many applications. Keith Szolusha, LED driver applications manager and Kyle Lawrence, associate applications engineer, identified the challenges for machine vision flash applications and propose a solution example with Analog Devices' LT3932 high speed LED driver.

Transparent Material Considerations for UV Optics in Horticultural Lighting Applications
Advancements in UV LED technology have begun changing the horticultural lighting landscape. Research is still ongoing to discover the extent of benefits and best practices of using UV light in horticulture. Using optics in tandem with UV LED light systems can help reach performance goals and optimize growing. Although there are several UV- transmitting materials available, not all are equivalent or able to meet the requirements for UV applications. Justine Galbraith, glass engineer, and Sharayah Follett, market development manager at Kopp Glass, Inc. discuss the performance considerations of various UV-transmitting materials and how application challenges are addressed by integrating optical elements.

WHITE PAPER - Measuring Color Uniformity
The color uniformity of light generated by LED luminaires plays a major role in many lighting applications. This makes it an important parameter to measure in both the R&D stage and during the quality assurance process. MKS Instruments has stayed abreast of this challenge by developing a new feature for its FluxGage photometrical system: the color uniformity measurement function. It allows quick evaluation of optical assemblies for color mixing and beam shaping. This whitepaper presents this novel feature of the system.

LRC Evaluates Hybrid UV/Blue Light Lighting System to Reduce Healthcare-Associated Infections
People who visit hospitals are expecting care and treatment, not additional complications, yet approximately 1 in 25 patients contract healthcare-associated infections (HAIs) in U.S. hospitals, according to the Centers for Disease Control and Prevention (CDC). Standard cleaning procedures usually involve manual application of detergents and disinfectants. Unfortunately, the efficacy of these manual cleaning procedures can vary considerably. In fact, less than 50% of patient room surfaces are properly cleaned.
