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 DC motor goniometers are suited for applications that require smooth motion, high speed and high repeatability.
•±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
•DC motor and rotary encoder for smooth motion and high repeatability
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.
