The BGM80CC by Newport is a Goniometric Cradle that is optimal for rotational applications, offering an exceptional degree of accessibility to the rotating components. This innovative cradle design allows for the assembly of compact multi-axis rotation systems. The cradle's pivotal movement occurs around a transverse axis positioned above the platform. The cradle's engineering enables the possibility of creating two perpendicular axes of rotation about a shared spatial point when two adjacent cradles are orthogonally mounted. Furthermore, by integrating a rotation stage beneath the assembly, a third orthogonal rotation axis can be introduced through the same central point. With an impressive angular resolution of 0.001 degrees, the BGM80CC is capable of accommodating various configuration options, including DC motors, manual drives, and mini-step or full-step drive motors. These configurations support rotational speeds of up to 20 degrees per second. The cradle's seamless rotation is upheld by precision-ground tool-steel races and single-row ball bearings, ensuring minimal wobble and eccentricity during operation. Convenience and precision converge with the inclusion of a central home feature, facilitating the straightforward return of the platform to a level position.
