Beam Profiling: What Is Your Laser Not Telling You? While it may seem intuitive that turning up the power on a laser will produce faster results in a materials processing operation, beam measurement tools often reveal that this only distributes the...
The Food Industry’s Appetite for Hyperspectral Imaging Grows If the old maxim “you are what you eat” has any truth to it, then it becomes critically important to ensure that the food you consume is safe and of suitable quality. To this end, the U.S. Department...
Camera Selection for Low-Light Imaging Fluorescence microscopy is a broadly used term, with applications ranging from basic life science, such as time-lapse cell viability assays, to sophisticated techniques in which a very few photons or...

Editorial
Light, photonics, and human health The correlation between light and human health should come as no surprise. Midsummer corresponds to an increase in outdoor activities. The summer growing season makes fresh produce a more abundant part of our daily diet. And, studies have shown that the extended daylight around the summer solstice, by itself, has proportionately positive effects on everything from mood to productivity to...
Photonic Fundamentals
Evaluating Off-the-Shelf Optical Components Off-the-shelf optical components offer a number of advantages for optical system design, including shorter delivery times, lower costs, and quicker replacement. These readily available optical products, however, are seldom used in custom optical designs. One reason is that no clear or uniform methodology exists to determine how effectively such optics will perform in a real-world optical...

White Solar-Reflectance Paint Reduces Need for Air Conditioning A team from Purdue University has developed an improved ultrawhite paint that, tests showed, reflected more than 98% of sunlight — compared to 95.5% of sunlight that an earlier version of the paint reflected following its introduction in October 2020. Applied to, or coated on a surface, the paint also directs incoming infrared heat away from the surface. The paint is poised to lessen the...

Fiber Lasers Put Their Print on the Marking Industry The commercial use of lasers for marking first appeared in the 1970s and was based on solid-state Nd:YAG and CO2 sources. The laser technologies offered a novel and attractive, noncontact, consumable-free marking process for a broad range of materials. Initial offerings were expensive and dogged with maintenance issues, but the evolution of the technology steadily made lasers the first choice for...

Light-powered GPS collar removes tether to batteries Catching bison is a hassle. It’s also expensive. For most, these truths are intuitive — just think about how big the net would have to be — but for a few, the knowledge comes firsthand. Researchers from the World Wide Fund for Nature (WWF) Ukraine, who have direct experience catching the creatures, recently worked with Saule Technologies to develop special bison-tracking collars...
