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.

The COE (Cryo Optical Encoder) is a fiber based optical encoder that can be added to selected positioners for position feedback. It works by illuminating a grid and detecting high/low intensity transitions from features in the grid. Resolution is determined by the pitch of these features. It is an incremental encoder, which means that it will reset to “zero” at a power shutdown. The COE requires the OEM electronics module as light source and position readout.
