The Cryo Bearing Stage (CBS) is a robust linear stage for all-round applications in a cryo-vacuum and will run both horizontally and vertically. The combination of long range stepping motion and short range scanning offers nm positioning over the full range. The use of non-magnetic materials allows operation in high magnetic fields. It is equipped with high performance full ceramic linear roller guides for maximum stiffness and mechanical stability. The guides are spring preloaded, ensuring consistent performance with playfree and smooth running from ambient to cryogenic temperatures.
