A new study shows that athletes who are exposed to blue light before competing can significantly improve their end performance. Researchers at the University of Basel’s Department of Sport, Exercise and Health investigated whether light exposure before a cycling time trial could compensate for the time of day the event was. According to their research, many sporting events take place late in the evening and many athletes fail to perform at their best due to their sleep-wake cycle. Seventy-four young male athletes participated in the study. Athletes in blue light: Performance...Read full articleRelated content from Photonics MediaARTICLESSmart Microscope Teaches Itself Settings for Diagnosing DiseaseEngineers at Duke University used machine learning to develop a microscope capable of adapting its lighting angles, colors, and patterns while teaching itself the optimal settings needed to complete...BioPhotonics Jan/Feb 2020 IssueActive Substance Optically Manipulates Component of CytoskeletonAn international research team from Jena, Munich, and New York has used photopharmacology — the use of light to switch the effect of drugs on and off — to control actin, a component of...BioPhotonics Jul/Aug 2020 IssueBioprinting System Uses Light Sheet Lithography for Living TissueA European consortium is developing a lithography method for bioprinting tissue and organs that uses light sheet illumination and photosensitive hydrogels mixed with living cells.

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 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 HandbookInterferometry: Measuring with Light: Long applied to optical shop testing, interferometry is now used to measure many different types of parts in a variety of applications, such as optical system performance, surface roughness, surface form, and displacement of moving surfaces.An interferometer is an instrument that compares the position or surface structure of two objects.
