By Vivek Komaragiri, chief technology officer, Sensory Analytics This article discusses some of the coating-process digitization opportunities created by real-time measurement of coating-thickness measurement data, especially by using a precise and absolute thickness-measurement technology known as ruggedized optical interference (ROI) technology. To remain competitive in a … [Read more...] about Coating-process digitalization opportunities created by absolute, in-process, coating-thickness measurement data

UV-LED measurement solutions for adhesive-curing applications
By Jim Raymont, director of sales, EIT 2.0 LLC UV LEDs with peak spectral outputs between 365-405 nanometers (nm) increasingly are 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 – … [Read more...] about UV-LED measurement solutions for adhesive-curing applications
Image-based speed and length measurement method for roll-to-roll manufacturing
By Takayuki Uozumi, optical engineer, Canon, Inc. In roll-to-roll (R2R) manufacturing, accurate control of web speed is important for coating & laminating processes, and length management is critical for cutting processes. To measure speed and length, rotary encoders, which rely on physical contact with the surface of the products, are widely used in roll-to-roll … [Read more...] about Image-based speed and length measurement method for roll-to-roll manufacturing
