A new, series of Dual-axis Yaw-and-Pitch Stages have been introduced by Optimal Engineering Systems, Inc. (OES). This new series of high precision Yaw-and-Pitch stages are suitable for precise measurements of compound curves and angles of an object during inspection or reverse engineering, laser machining and drilling, scanning, tracking, mirror positioning, and for use with coordinate measuring machines and autocollimators.
The YP100-45 Series of Yaw-and-Pitch Stages were developed through the integration of a rotary stage (yaw axis) and a goniometer (pitch axis) having a travel range of +/- 45°.
Four motor options are available. They include Stepper Motor driven axes (-01 version), Three Phase-Servo Motor driven Axes (pictured, -02 version), DC Servo Brushed Motor Driven Axes (-03 version) and Stepper Motor Driven Axes with Quadrature Optical Encoders (-04 version) for position verification.
The -01 and -04 versions have a maximum speed of 14° per second and have a resolution of 0.001° when 10 Micro-steps per Step Motor Drivers are used. The positional accuracy is 0.05°, and repeatability is +/-0.01°. The -04 version has Quadrature Incremental Encoders mounted on the stepper motors for position verification. For higher speeds up to 45° per second, greater accuracy, repeatability, and resolution, either the YP100-45-02, or -03 Stages should be selected. They are driven by brushed or brushless Servo Motors with Quadrature Incremental Encoders for closed loop servo operation.
The yaw axis is equipped with a HOME switch to signal the motion controller HOME position. The pitch axis has end of limit switched. Both axes have a calibrated scale for visual inspection.
The pitch axis table is 90 mm x 104 mm and has a precision pattern of threaded holes for mounting tooling or fixtures. The large predrilled base plate facilitates mounting in new or existing applications and adds to the stability of the stage.
Each of these Yaw-and-Pitch Stages can be ordered with a plug-and-play, fully compatible motion controller for any motor combination from OES.
