High Precision Motorized Goniometric Cradles B G S e r i e S

Product catalog summary

Overview: The document provides detailed specifications and features of the BG Series High Precision Motorized Goniometric Cradles, designed for tip and tilt applications. These cradles allow for precise rotation and are suitable for stacking to achieve orthogonal rotation about a common pivot point.

Specifications: The BG Series offers up to ±45° transverse axis rotation with mechanical limit switches. The precision worm gear drive ensures non-backdrivable motion with high accuracy and repeatability. The stages are vacuum compatible up to 10^-6 hPa.

Design Details: The cradles are constructed with stainless steel and aluminum, featuring ball bearings for smooth motion. The worm gear ratio varies across models, with feedback provided by rotary encoders. Limit switches are mechanical, and an optical origin is set at 0°.

Performance: The cradles are available in DC motor and stepper motor versions, each offering different advantages in terms of torque, speed, and repeatability. The DC motor versions provide higher torque and repeatability, while the stepper motor versions are suited for higher speed applications.

Load Characteristics and Stiffness: The document details the load capacity, construction parameters, radial compliance, and maximum torque for each model. The cradles are designed to handle significant loads with minimal wobble and high stability.

Assembly and Interfaces: The document includes detailed assembly patterns and interface dimensions for stacking BG Series stages with other Newport stages. It provides specific measurements for accessing interface holes and mounting configurations.

Recommended Controllers/Drivers: Several models of motion controllers and drivers are recommended for use with the BG Series, including the XPS-D, XPS-DRV11, and SMC100 series.

Ordering Information: The document provides a guide for ordering different models, specifying motor types and vacuum compatibility. It also includes dimensions and mounting details for various models.

High Precision Motorized Goniometric Cradles SP 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. • ±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 smooth motion and high stability Open Rotation Platform The BGS 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. • Precision ground worm gear provides 0.002° MIM • Vacuum compatible versions up to 10-6 hPa Precision Worm Gear Drive Precise rotation is ensured by a precision ground, hardened worm gear drive. In addition to being non-backdrivable, the worm gear drive's advantages include higher MIM, repeatability, and overall accuracy. Screw (worm) Gear (Wheel) Direct Mounting Interface BG cradles are designed so that two adjacent-sized models mounted orthogonally, such as BGS80 with BGM120, pivot about the same point in space. For a third rotation axis, yaw for example, a rotation stage can be mounted under the assembly. The direct mounting capability saves set-up time, design time, and adapter plate costs. Ball Bearings with Tool-Steel Races Single-row ball bearings and precision-ground, hardened tool-steel races ensure smooth rotation with minimal wobble and eccentricity. This allows for higher load capacities, stiffness, an

Performance DC Motor and Encoder Versions The BG cradles are available in DC motor versions, which results in higher torque and repeatability. All encoders come with index pulses for precision homing. The BGS50CC uses a miniature DC servo motor, kept in a compact, lightweight package. All other models feature a high resolution, worm mounted rotary encoder which bypasses most drive train errors, resulting in improved bi-directional repeatability. The BGM models use high torque DC motors with a built-in tachometer to provide superior speed stability. Stepper Motor Versions The PP mini-step drive...
