Eight new Yaw-and-Pitch stages have been introduced by OES (Optimal Engineering Systems, Inc.). These new series of high precision Yaw-and-Pitch Stages integrate goniometers as the lower stage (yaw axis) and a rotary stage as the upper stage (pitch axis). The yaw range of travel is +/- 10 or +/- 15 degrees, with the pitch range of travel being 360 degrees of continuous motion. The diameter of the pitch axis is 60 mm.

There are four motor options for both the YP10-60 and the YP15-60 Yaw and Pitch series stages They include: stepper motors (-01 version pictured), three-phase brushless servo motors with quadrature optical encoders (-02 version), dc servo brushed motors with quadrature optical encoders (-03 version), and stepper motor driven axes with quadrature optical encoders (-04 version) for position verification.

The -01 and -04 versions of each stage have a maximum speed of 14 degrees per second and have a resolution of 0.001 degrees when 10 micro-steps per step motor drivers are used.  The positional accuracy is 0.05 degrees, and repeatability is +/-0.01 degrees. The -04 version has quadrature incremental encoders mounted on the stepper motors for position verification.  Select either the -02, or -03 motor options for higher speeds up to 45 degrees per second, greater accuracy, repeatability, and resolution gained from servo motors in a closed loop.

The pitch axis is equipped with a HOME signal for initialization and the yaw axis has end of limit switches. Both axes have calibrated scales to display the angle of rotation. The stages can be ordered with a plug-and-play, fully compatible motion controller for any motor combination from OES.

Applications include laser scanning, drilling, and machining, reverse engineering, inspection, assembly, measurements, tracking, and positioning.
