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
