Precision Manufactured

All of our calibration targets are made from aluminium/LDPE composite sheets which offers excellent flatness and stiffness, while being lightweight. Additionally, the composite material offers good thermal stability and corrosion resistance.  

The patterns are transferred to the composite material using a specialised precision direct UV (Ultra-Violet) printing process resulting in a durable matte finish. Through extensive testing, we have found this process to be ideal for machine vision applications, where both accuracy, good optical performance and physical robustness are of utmost importance.
