This manual introduces the features and characteristics of the SR50 series compact high resolution rotation stages.
This user manual provides instructions for operating the Newport Corporation SR50 Series compact high-resolution rotation stages, designed for rotating optical components up to 1 inch in diameter. The stages feature a low-profile aluminum body with pre-loaded ball bearings and a precision ground worm gear for smooth, precise rotation. Two versions are available: SR50CC with DC servo motor and encoder feedback, and SR50PP with stepper motor and open-loop control. The manual includes safety warnings, connection guidelines, maintenance procedures, and specifications for mechanical and electrical operation.
The SR50 stages are RoHS compliant and designed for use in confined spaces such as laser cavities or fiber optic manufacturing. They offer angular resolution of 0.001° and can operate in continuous rotation mode. Connection to Newport controllers is recommended for optimal performance, and the stages come with a 3-meter cable. Maintenance and calibration are advised annually, and warranty coverage is one year from shipment.
