Specification and Applications for ProLight Opto's Recently Released UV-C LEDs
Escalation of the Coronavirus outbreak have led to higher demand for Ultra-Violet C (UV-C) LED around the world. UV-C as a germicidal light source can inactivates microorganisms by destroying nucleic acids and disrupting their DNA with its short wavelength. The effective germicidal wavelength is between 200-290 nm; shorter wavelength is more efficient but is also more damaging to the human body. The major chip manufacturers make 265-285 nm as mainstream wavelength, because it can improve single chip's radiometric power and increase in sterilization efficiency.

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.

Measuring the Oxygen Content of Blood with LEDs
Pulse oximetry is a non-invasive method for determining haemoglobin (Hb) saturation through oxygen in the blood and heart frequency. It uses the fact that oxygen-rich and oxygen-poor haemoglobin absorb red and infrared light differently. In order to measure the oxygen content reliably, LEDs with high performance, constant quality and low scattering are needed as light sources. With the WL-SMTW and WL-SITW series, Würth Elektronik has suitable red and infrared LEDs in its portfolio. In addition, there is a matching light sensor available: The phototransistor WL-STTW can reliably detect both red and infrared light.
