The upcoming midterm elections in the US, along with the continuous doublespeak from both sides of the political aisle, are the inspiration for this quarter’s column. I no longer wonder why most internet polls rank politicians as one of the least trusted professions. The only campaign promise I have believed was on the button at the top of this page. Do we “stretch the … [Read more...] about Little Purple Lies in UV

Let’s Do a Deep Dive…on Underwater Strobes, UV Sources, Measurement and Reliability
This quarter’s column was inspired by an underwater photography blog (“How Good Are the Strobes for Light Intensity and Coverage?”1), generated by Reef Photo & Video in Florida. My first thought when reading was that it could double as a UV curing blog. For 47 years, my definition of a “deep dive” has been a dive deeper than 60 feet (18 meters). Let’s see if I can do a … [Read more...] about Let’s Do a Deep Dive…on Underwater Strobes, UV Sources, Measurement and Reliability
LED Measurement Solutions for Adhesive Applications
UV LEDs with peak spectral outputs between 365-405 nanometers (nm) are increasingly being used to cure adhesives, but converting a process from mercury to LED may involve more than “turning on” an LED and “turning off” a mercury source. It is important to work with your supplier/formulator to test, evaluate and – if needed – make changes to the formulation. Three parameters A … [Read more...] about LED Measurement Solutions for Adhesive Applications
UV LED curing systems: Measuring accurately and eliminating safety hazards
By Geri Tangdiongga, Don Moncy Dominic and Dominik Stephan, Dymax Asia Pacific Pte. Ltd. Abstract Ultraviolet (UV) LED technologies are progressing very rapidly in recent years, both in performance and cost. Therefore, the measurement equipment and methods for UV LED curing systems must be well understood. This paper focuses on the measurement and characterization of the UV … [Read more...] about UV LED curing systems: Measuring accurately and eliminating safety hazards
Q. Why Measure UV LEDs?
I was drafted (volunteered) to take this column over from Dick Stowe when he finally convinced the editors of UV+EB Technology that he wanted to slow down a little. We owe Dick a big thanks for the work he has done to educate and help users understand UV technology, measurement and process control. He has done this not only with this column but over a long career, and I have … [Read more...] about Q. Why Measure UV LEDs?
