Raman Spectroscopy Dishes Up Solutions for the Food Industry As people, we have a complex relationship with food. We want it to be simple, cost-effective, and convenient. But we also savor gourmet foods prepared with the finest ingredients available. The...
Ultrafast Lasers Are Quickly Catching Up with Industry Demand With pulse lengths down to the picosecond realm and beyond, ultrashort-pulse lasers — often called ultrafast lasers — have been deployed as scientific research tools for decades. The...
How Far Down the Road Is the Autonomous Vehicle? First conceived by editors of Scientific American magazine, the dream of self-driving cars — known today as autonomous vehicles (AVs) — recently passed its 100-year anniversary. With the...
Managing Temperature-Based Performance Drift for Coatings What happens when optical coatings get very cold? There should be little difference in a thin film’s optical performance at room temperature test conditions versus its use conditions. But this is not...
Editorial
Trust science to ask the right questions As has been noted recently on this page, evidence-based thinking and science could stand a little more advocacy these days. Hopefully, for most readers of this publication, the question is not why but how this advocacy should be exercised. One simple step would be to join Nobel laureates, global educators, scientists, engineers, and many others by adding your name to the Trust Science pledge at...
Lasers In Use
What Ever Happened to Medical Surveillance? Did you know there was a time when eye exams were suggested every three years for users of Class 3B or Class 4 lasers? The rules around so-called medical surveillance began to change in 2007, when the American National Standards Institute’s (ANSI) laser standards ceased to require baseline eye examinations for users of these laser classes. What happened to cause this change? To answer, let...

Lighter Side
Dude, your temporary tattoo is lit! For a kid growing up in the ’90s, few things were better than running around in light-up sneakers that emitted a rhythmic glow with every footfall, while brandishing arms covered in temporary tattoos of favorite superheroes and cartoon characters. Fortunately, or unfortunately, vestiges of the ’90s are seeing a comeback: pastel windbreakers, Midwest emo, the fashion of the Seattle...
