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 substrate is carefully machined to size and fitted with 6mm corner radiuses to maximize robustness. 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.
To mount or position these targets on tripod, frames or fixtures, see Accessories.
For further information, please refer to the aluminium composite datasheet.
