Aluminium composite targets
Our larger sized 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.
Ceramic targets
For ultimate absolute accuracy requirements and smaller FOVs, we offer ceramic targets. These are extremely flat, have close no to thermal expansion, and are manufactured on semi-conductor clean-room lithography lines.
In order to provide good, matte contrast without specular highlights, we use a specially coated blue chrome coating on a white alumina ceramic substrate. Feature-to-feature dimensional accuracy is better than 10μm.
Please note: we are also able to manufacture ceramic calibration targets with other patterns or designs at dimensions up to 400x400mm. NRE costs apply. Please submit a quote request if interested.
For further information, please refer to the ceramic datasheet.
