High Precision Stepper Motor Goniometers
High Precision Stepper Motor Goniometers
For tip and tilt applications, the BG series of goniometers allows open access to the load. When two BG stage are stacked together, the sample rotates about a common pivot point. These stepper motor goniometers are suited for applications that require higher output torque. Vaccum compatible versions up to 10-6 hPa are also available.
- ±45° transverse axis rotation with maximum free access to the rotating platform
- Stacked cradles provide orthogonal rotation about the same pivot point
- Precision machined ball bearing races assure high stability and stiffness with minimal wobble
- Precision ground worm gear provides 0.002° MIM
- Stepper motor for higher torque, and 10-6 hPa vacuum compatible versions available See All Features

Features
Precision Multi-Axis Assemblies
BG goniometers are designed so that two adjacent-sized models can be directly mounted orthogonally to each other (for example, BGS80 with BGM120) to pivot about the same point in space. The direct mounting capability saves set-up time, design time, and adapter plate costs. For additional rotation axes, a rotation stage can be mounted under the assembly or on the top BG platform. The video demonstrates an open access, multi-axis tip, tilt and rotation assembly with two BG goniometers and two rotation stages.
Open Rotation Platform
The BG series stages provide up to ±45° of transverse axis rotation enforced with mechanical limit switches. The stage is designed for maximum free access to the rotating platform, allowing for simplified stacking and mounting.

Stepper Motor Versions
The PP and BPP mini-step drive versions are for applications that require higher speeds. For higher torque and vacuum applications, the PE and BPE full-step drive versions are recommended.
CONEX Controller Version
Newport also offers a version of the DC motor, 50-mm2 platform goniometer with integrated CONEX controller, the CONEX-BGS50CC. For out-of-the box control, the CONEX controller is preconfigured and delivered with the BGS50CC goniometer.
Vacuum Compatible Versions
The (M-)BGM120PEBV6 and (M-)BGM160PEBV6 are the vacuum compatible versions of the BG stepper motor goniometers. They can be used in a vacuum environment down to 10-6 hPa. Their performance is similar to their corresponding BGM-PE stepper motor goniometer.
