Product description
The Cryo Linear Drive (CLD) is a linear stage with an unrivaled 51.5 mm coarse stroke and close to 2 micron scanning range in a compact and robust package. This offers a solution for long stroke applications in cryogenic positioning. Optionally an optical encoder can be fitted for closed loop control. Moving parts are made out of non-magnetic phosphor bronze to minimize interaction with external magnetic fields.
